Originally I thought interleaving AIR with MIR will be useful, however
as it stands, I have used it very sporadically, and recently, not at
all, and I do not think anyone else is actually using it. If there is
a simple error such as a wrong instruction emitted,
`objdump` is perfectly capable of narrowing it down, while if there's
something more subtle happening, regardless of having `--verbose-mir`
functionality or not, you still gotta go via the debugger which
offers a better view at interleaved source program with the emitted
machine code. Finally, I believe `-femit-asm` when we add it will offer a
more generic substitute.
While calling `next` an error can occur while parsing the file.
However, we don't set the filename that is currently being processed, until `next` completed successfully.
This means that for invalid test names, the wrong filename was being displayed in the panic message.
The fix is to retrieve the correct filename when an error occurs and then setting the filename appropriately.
This matches master branch. We can look into adding more target coverage
as we switch to stage2. As it stands, this works around having to
duplicate the "Executor" logic to figure out when to not run the tests
due to them being non-native.
* 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.
Rename all references of sparcv9 to sparc64, to make Zig align more with
other projects. Also, added new function to convert glibc arch name to Zig
arch name, since it refers to the architecture as sparcv9.
This is based on the suggestion by @kubkon in PR 11847.

the list parameter should be a multi-item pointer rather than a single-item
pointer. see: https://linux.die.net/man/2/setgroups
> setgroups() sets the supplementary group IDs for the calling process...
> the size argument specifies the number of supplementary group IDs in the buffer pointed to by list.
The "slicing operator with sentinel" runtime safety test cases should
all have been compile errors in their current forms. In this commit I
adjust them to use runtime-known slices before triggering the runtime
safety.
Furthermore the test cases did not actually have unique names.
- Test: Fix bucket counting. Previously, the first hit was not counted.
This off-by-one error slightly increased the mean of `*_total_variance`,
which decreased the acceptance rate for a particular random seed
from 95% to 92.6%. (Irrelevant for test failure because the seed is fixed.)

EnvMap provides the same API as the previously used BufMap (besides `putMove` and `getPtr`), so usage sites of `getEnvMap` can usually remain unchanged.
For non-Windows, EnvMap is a wrapper around BufMap. On Windows, it uses a new EnvMapWindows to handle some Windows-specific behavior:
- Lookups use Unicode-aware case insensitivity (but `get` cannot return an error because EnvMapWindows has an internal buffer to use for lookup conversions)
- Canonical names are returned when iterating the EnvMap
