The purpose of this test is unclear. It checks for the existence of bss
section which is completely unnecessary since those zeroes can be
omitted from the binary.
Furthermore the code generated for __wasm_init_memory looks wrong.
Finally, the CheckObject DSL is brittle, it only checks for exact
matches of entire lines in an ad-hoc text format. Conclusion, it's a bad
test, delete it.

Introduce the concept of "target query" and "resolved target". A target
query is what the user specifies, with some things left to default. A
resolved target has the default things discovered and populated.
In the future, std.zig.CrossTarget will be rename to std.Target.Query.
Introduces `std.Build.resolveTargetQuery` to get from one to the other.
The concept of `main_mod_path` is gone, no longer supported. You have to
put the root source file at the module root now.
* remove deprecated API
* update build.zig for the breaking API changes in this branch
* move std.Build.Step.Compile.BuildId to std.zig.BuildId
* add more options to std.Build.ExecutableOptions, std.Build.ObjectOptions,
std.Build.SharedLibraryOptions, std.Build.StaticLibraryOptions, and
std.Build.TestOptions.
* remove `std.Build.constructCMacro`. There is no use for this API.
* deprecate `std.Build.Step.Compile.defineCMacro`. Instead,
`std.Build.Module.addCMacro` is provided.
- remove `std.Build.Step.Compile.defineCMacroRaw`.
* deprecate `std.Build.Step.Compile.linkFrameworkNeeded`
- use `std.Build.Module.linkFramework`
* deprecate `std.Build.Step.Compile.linkFrameworkWeak`
- use `std.Build.Module.linkFramework`
* move more logic into `std.Build.Module`
* allow `target` and `optimize` to be `null` when creating a Module.
Along with other fields, those unspecified options will be inherited
from parent `Module` when inserted into an import table.
* the `target` field of `addExecutable` is now required. pass `b.host`
to get the host target.

Disable garbage-collection for certain tests to ensure the tested
sections are being emitted.

This updates all linker tests to include `no_entry` as well as changes
all tests to executable so they do not need to be updated later when
the in-house WebAssembly linker supports dynamic libraries.

Instead, we now have a looser helper called `checkContains(...)`
that will match on any occurrence similarly to `std.mem.indexOf()`.
While at it, I have cleaned up other combinators to make the entire
API more consistent, and so:
* `checkStart(phrase)` is now `checkStart()` followed by
`checkExact(phrase)`
* `checkNext(phrase)` if matching exactly is now `checkExact(phrase)`
* `checkNext(phrase)` if matching loosely is now `checkContains(phrase)`
* `checkNext(phrase)` if matching exactly with var extractors is now
`checkExtract(phrase)`
Finally, `ElfDumper` is now dumping contents of `.symtab` and `.dynsym`
symbol tables. I have also removed dumping of symtabs as optional - they
are now always dumped which cleaned up the implementation even more.

Updates the linker test to verify the various cases where we must
store the data in the bss segment.

Instead of using `zig test` to build a special version of the compiler
that runs all the test-cases, the zig build system is now used as much
as possible - all with the basic steps found in the standard library.
For incremental compilation tests (the ones that look like foo.0.zig,
foo.1.zig, foo.2.zig, etc.), a special version of the compiler is
compiled into a utility executable called "check-case" which checks
exactly one sequence of incremental updates in an independent
subprocess. Previously, all incremental and non-incremental test cases
were done in the same test runner process.
The compile error checking code is now simpler, but also a bit
rudimentary, and so it additionally makes sure that the actual compile
errors do not include *extra* messages, and it makes sure that the
actual compile errors output in the same order as expected. It is also
based on the "ends-with" property of each line rather than the previous
logic, which frankly I didn't want to touch with a ten-meter pole. The
compile error test cases have been updated to pass in light of these
differences.
Previously, 'error' mode with 0 compile errors was used to shoehorn in a
different kind of test-case - one that only checks if a piece of code
compiles without errors. Now there is a 'compile' mode of test-cases,
and 'error' must be only used when there are greater than 0 errors.
link test cases are updated to omit the target object format argument
when calling checkObject since that is no longer needed.
The test/stage2 directory is removed; the 2 files within are moved to be
directly in the test/ directory.

I've been wanting to do this for along time.

Adds a linker test case for each possible export case. This means
one where no exports are done (i.e. no flags set), when the -dynamic
flag is set, and finally when --export=<value> flag(s) are set.

After this commit, the self-hosted compiler does not offer the option to
use stage1 as a backend anymore.

* 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.
