The meaning of this "skip_stage2" flag was intended to mean the
self-hosted backends, not the stage2 frontend. Sorry for the confusion.

* accept forward and backward slashes in file paths
* strip multiple extensions; e.g. if the basename is "test.exe.obj"
then it strips to "test".

stage1 is available behind the -fstage1 flag.

* test/link: initial wasm support
This adds basic parsing and dumping of wasm section so they
can be tested using the new linker-test infrastructure.
* test/link: all wasm sections parsing and dumping
We now parse and dump all sections for the wasm binary format.
Currently, this only dumps the name of a custom section.
Later this should also dump symbol table, name, linking metadata and relocations.
All of those live within the custom sections.
* Add wasm linker test
This also fixes a parser mistake in reading the flags.
* test/link: implement linker tests wasm & fixes
Adds several test cases to test the wasm self-hosted linker.
This also introduces fixes that were caught during the implementation
of those tests.
* test-runner: obey omit_stage2 for standalone
When a standalone test requires stage2, but stage2 is omit
from the compiler, such test case will not be included as part
of the test suite that is being ran. This is to support CI's
where we omit stage2 to lower the memory usage.

* migrate runtime safety tests to the new test harness
- this required adding compare output / execution support for stage1
to the test harness.
* rename `zig build test-stage2` to `zig build test-cases` since it now
does quite a bit of stage1 testing actually. I named it this way
since the main directory in the source tree associated with these
tests is "test/cases/".
* add some documentation for the test manifest format.

We can't yet run the behavior tests with stage3, but at least we can run
them with stage2, and we can use the proper test matrix.
This commit also adds use_llvm and ofmt to the zig build system.

Instead, just return ChildProcess directly. This structure does not
require a stable address, so we can put it on the stack just fine. If
someone wants it on the heap they should do.
const proc = try allocator.create(ChildProcess);
proc.* = ChildProcess.init(args, allocator);

In accordance with the requesting issue (#10750):
- `zig test` skips any tests that it cannot spawn, returning success
- `zig run` and `zig build` exit with failure, reporting the command the cannot be run
- `zig clang`, `zig ar`, etc. already punt directly to the appropriate clang/lld main(), even before this change
- Native `libc` Detection is not supported
Additionally, `exec()` and related Builder functions error at run-time, reporting the command that cannot be run

An attempt to normalize some of the function names in build.zig. Normalize add*Dir to add*Path. Also use "Library" instead of the "Lib" abbreviation.
The PR does not remove the old names, only adds the new normalized ones to faciliate a transition period.

See the commit message of 5b6d26e97bb97d79782f3c77b02a997e361a1497 for
an explanation. This is the same thing but for powerpc instead of mips.

Before this commit, glibc headers did the following mapping:
* (zig) mipsel-linux-gnu => (glibc) mipsel-linux-gnu
* (zig) mipsel-linux-gnu-soft => (glibc) (none)
* (zig) mips-linux-gnu => (glibc) mips-linux-gnu
* (zig) mips-linux-gnu-soft => (glibc) (none)
While the glibc ABI stubs used the (zig) gnueabi and gnueabihf ABIs,
and the stage2 available_libcs array listed:
* (zig) mipsel-linux-gnu
* (zig) mips-linux-gnu
The problem is the mismatch between the ABI component of the headers and
the stubs.
This commit makes the following clarifications:
* (zig) mips-linux-gnueabi means soft-float
* (zig) mipsel-linux-gnueabi means soft-float
* (zig) mips-linux-gnueabihf means hard-float
* (zig) mipsel-linux-gnueabihf means hard-float
Consequently, the glibc headers now do this mapping:
* (zig) mips-linux-gnueabihf => (glibc) mips-linux-gnu
* (zig) mipsel-linux-gnueabihf => (glibc) mipsel-linux-gnu
* (zig) mips-linux-gnueabi => (glibc) mips-linux-gnu-soft
* (zig) mipsel-linux-gnueabi => (glibc) mipsel-linux-gnu-soft
The glibc ABI stubs are unchanged, and the stage2 available_libcs
array's 2 entries are modified and it gains 2 more:
* (zig) mipsel-linux-gnueabi
* (zig) mipsel-linux-gnueabihf
* (zig) mips-linux-gnueabi
* (zig) mips-linux-gnueabihf
Now everything is consistent. Zig no longer recognizes a `mips-linux-gnu`
triple; one must use `mips-linux-gnueabi` (soft float) or
`mips-linux-gnueabihf` (hard float).

from zig-specific options to generally recognized zig build options that
any project can take advantage of. See the updated usage text for more

Add `aarch64-macos-gnu` corresponding test case.
Fix rebase gone wrong.

Like QEMU or Wine, you need to declare you want Rosetta
enabled for running tests/build artifacts via `-Denable-rosetta`
flag.

This way, we can explicitly signal if a test requires the presence
of macOS SDK to build. For instance, when testing our in-house
MachO linker for correctly linking Objective-C, we require the
presence of the SDK on the host system, and we can enforce this
with `-Denable-macos-sdk` flag to `zig build test-standalone`.

The motivation for this commit is that there exists source files which
produce ast-check errors, but crash stage1 or otherwise trigger stage1
bugs. Previously to this commit, Zig would run AstGen, collect the
compile errors, run stage1, report stage1 compile errors and exit if
any, and then report AstGen compile errors.
The main change in this commit is to report AstGen errors prior to
invoking stage1, and in fact if any AstGen errors occur, do not invoke
stage1 at all.
This caused most of the compile error tests to fail due to things such
as unused local variables and mismatched stage1/stage2 error messages.
It was taking a long time to update the test cases one-by-one, so I
took this opportunity to unify the stage1 and stage2 testing harness,
specifically with regards to compile errors. In this way we can start
keeping track of which tests pass for 1, 2, or both.
`zig build test-compile-errors` no longer works; it is now integrated
into `zig build test-stage2`.
This is one step closer to executing compile error tests in parallel; in
fact the ThreadPool object is already in scope.
There are some cases where the stage1 compile errors were actually
better; those are left failing in this commit, to be addressed in a
follow-up commit.
Other changes in this commit:
* build.zig: improve support for -Dstage1 used with the test step.
* AstGen: minor cosmetic changes to error messages.
* stage2: add -fstage1 and -fno-stage1 flags. This now allows one to
download a binary of the zig compiler and use the llvm backend of
self-hosted. This was also needed for hooking up the test harness.
However, I realized that stage1 calls exit() and also has memory
leaks, so had to complicate the test harness by not using this flag
after all and instead invoking as a child process.
- These CLI flags will disappear once we start shipping the
self-hosted compiler as the main compiler. Until then, they can be
used to try out the work-in-progress stage2.
* stage2: select the LLVM backend by default for release modes, as long
as the target architecture is supported by LLVM.
* test harness: support setting the optimize mode

- this one might be problematic; start.zig looks for `main` in the
root source file, not `_main`. Not sure why there is an underscore
there in master branch.

since the path to the tested binary is relative to cwd
* for the `zig test` command, we simply use `darling` since the

Mainly I wanted Jakub's new macOS code for respecting stack size, since
we now depend on it for debug builds able to pass one of the test cases
for recursive comptime function calls with `@setEvalBranchQuota`.
The conflicts were all trivial.

This is needed to catch any possible problem with executables linking to
32bit glibc.
|

In particular I wanted the change that makes `suspend;` illegal in the
parser.
