Only about half of the tests in std were actually being run (918 vs 2144).

AIR:
* `array_elem_val` is now allowed to be used with a vector as the array
type.
* New instructions: splat, vector_init
AstGen:
* The splat ZIR instruction uses coerced_ty for the ResultLoc, avoiding
an unnecessary `as` instruction, since the coercion will be performed
in Sema.
* Builtins that accept vectors now ignore the type parameter. Comment
from this commit reproduced here:
The accepted proposal #6835 tells us to remove the type parameter from
these builtins. To stay source-compatible with stage1, we still observe
the parameter here, but we do not encode it into the ZIR. To implement
this proposal in stage2, only AstGen code will need to be changed.
Sema:
* `clz` and `ctz` ZIR instructions are now handled by the same function
which accept AIR tag and comptime eval function pointer to
differentiate.
* `@typeInfo` for vectors is implemented.
* `@splat` is implemented. It takes advantage of `Value.Tag.repeated` 😎
* `elemValue` is implemented for vectors, when the index is a scalar.
Handling a vector index is still TODO.
* Element-wise coercion is implemented for vectors. It could probably
be optimized a bit, but it is at least complete & correct.
* `Type.intInfo` supports vectors, returning int info for the element.
* `Value.ctz` initial implementation. Needs work.
* `Value.eql` is implemented for arrays and vectors.
LLVM backend:
* Implement vector support when lowering `array_elem_val`.
* Implement vector support when lowering `ctz` and `clz`.
* Implement `splat` and `vector_init`.

We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.

Conflicts:

* src/link/SpirV.zig
* test/stage2/darwin.zig
- 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.

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.

Use std.builtins instead.

When the line has trailing whitespace we already print it with a
carriage return symbol at the end, don't print it one more time.

This makes a few changes to the base64 codecs.
* The padding character is optional. The common "URL-safe" variant, in
particular, is generally not used with padding. This is also the case for
password hashes, so having this will avoid code duplication with bcrypt,
scrypt and other functions.
* The URL-safe variant is added. Instead of having individual constants
for each parameter of each variant, we are now grouping these in a
struct. So, `standard_pad_char` just becomes `standard.pad_char`.
* Types are not `snake_case`'d any more. So, `standard_encoder` becomes
`standard.Encoder`, as it is a type.
* Creating a decoder with ignored characters required the alphabet and
padding. Now, `standard.decoderWithIgnore(<ignored chars>)` returns a
decoder with the standard parameters and the set of ignored chars.
* Whatever applies to `standard.*` obviously also works with `url_safe.*`
* the `calcSize()` interface was inconsistent, taking a length in the
encoder, and a slice in the encoder. Rename the variant that takes a
slice to `calcSizeForSlice()`.
* In the decoder with ignored characters, add `calcSizeUpperBound()`,
which is more useful than the one that takes a slice in order to size
a fixed buffer before we have the data.
* Return `error.InvalidCharacter` when the input actually contains
characters that are neither padding nor part of the alphabet. If we
hit a padding issue (which includes extra bits at the end),
consistently return `error.InvalidPadding`.
* Don't keep the `char_in_alphabet` array permanently in a decoder;
it is only required for sanity checks during initialization.
* Tests are unchanged, but now cover both the standard (padded) and
the url-safe (non-padded) variants.
* Add an error set, rename `OutputTooSmallError` to `NoSpaceLeft`
to match the `hex2bin` equivalent.

Beside handling NaNs and other non-numeric values better we finally
offer the same pair of testing predicates in math and testing.

std.crypto.random
* cross platform, even freestanding
* can't fail. on initialization for some systems requires calling
os.getrandom(), in which case there are rare but theoretically
possible errors. The code panics in these cases, however the
application may choose to override the default seed function and then
handle the failure another way.
* thread-safe
* supports the full Random interface
* cryptographically secure
* no syscall required to initialize on Linux (AT_RANDOM)
* calls arc4random on systems that support it
`std.crypto.randomBytes` is removed in favor of `std.crypto.random.bytes`.
I moved some of the Random implementations into their own files in the
interest of organization.
stage2 no longer requires passing a RNG; instead it uses this API.
Closes #6704

`std.GeneralPurposeAllocator` is now available. It is a function that
takes a configuration struct (with default field values) and returns an
allocator. There is a detailed description of this allocator in the
doc comments at the top of the new file.
The main feature of this allocator is that it is *safe*. It
prevents double-free, use-after-free, and detects leaks.
Some deprecation compile errors are removed.
The Allocator interface gains `old_align` as a new parameter to
`resizeFn`. This is useful to quickly look up allocations.
`std.heap.page_allocator` is improved to use mmap address hints to avoid
obtaining the same virtual address pages when unmapping and mapping
pages. The new general purpose allocator uses the page allocator as its
backing allocator by default.
`std.testing.allocator` is replaced with usage of this new allocator,
which does leak checking, and so the LeakCheckAllocator is retired.
stage1 is improved so that the `@typeInfo` of a pointer has a lazy value
for the alignment of the child type, to avoid false dependency loops
when dealing with pointers to async function frames.
The `std.mem.Allocator` interface is refactored to be in its own file.
`std.Mutex` now exposes the dummy mutex with `std.Mutex.Dummy`.
This allocator is great for debug mode, however it needs some work to
have better performance in release modes. The next step will be setting
up a series of tests in ziglang/gotta-go-fast and then making
improvements to the implementation.

Add functions for testing floats with margins and epsilons to standard library

by default the test runner will only print logs with "warning" or
higher. this can be configured via the std.testing API.

This commit generalizes `std.fs.wasi.PreopenList.find(...)` allowing
search by `std.fs.wasi.PreopenType` union type rather than by dir
name. In the future releases of WASI, it is expected to have more
preopen types (or capabilities) than just directories. This commit
aligns itself with that vision.
This is a potentially breaking change. However, since `std.fs.wasi.PreopenList`
wasn't made part of any Zig release yet, I think we should be OK
to introduce those changes without pointing to any deprecations.
