This regressed; the plan9 linker code is crashing when trying to build
compiler-rt and we have no active plan9 maintainers involved in the Zig
project. Anyone is welcome to come over and take the role; however, it's
not one of the tier 1, 2, or 3 targets, so we will not be blocking
progress towards 1.0 on plan9.
Prior to this change, for an example compiler error test case with
multiple identical errors messages such as
```
:1:2: error: foo
:1:2: error: foo
```
the test harness would never increment the error index thus only
marking the very first error message as handled yielding a false
positive.
Additionally, while here, regress `dereference_anyopaque` test case
as not passing on `wasm32-wasi` target.
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.

This commit contains everything from the copy-elision-2
branch that does not have to do with copy elision directly,
but is generally useful for master branch.
* All const values know their parents, when applicable, not
just structs and unions.
* Null pointers in const values are represented explicitly,
rather than as a HardCodedAddr value of 0.
* Rename "maybe" to "optional" in various code locations.
* Separate DeclVarSrc and DeclVarGen
* Separate PtrCastSrc and PtrCastGen
* Separate CmpxchgSrc and CmpxchgGen
* Represent optional error set as an integer, using the 0 value.
In a const value, it uses nullptr.
* Introduce type_has_one_possible_value and use it where applicable.
* Fix debug builds not setting memory to 0xaa when storing
undefined.
* Separate the type of a variable from the const value of a variable.
* Use copy_const_val where appropriate.
* Rearrange structs to pack data more efficiently.
* Move test/cases/* to test/behavior/*
* Use `std.debug.assertOrPanic` in behavior tests instead of
`std.debug.assert`.
* Fix outdated slice syntax in docs.
* bitreverse - give bswap behavior
* bitreverse, comptime_ints, negative values still not working?
* bitreverse working for negative comptime ints
* Finished bitreverse test cases
* Undo exporting a bigint function. @bitreverse test name includes ampersand
* added docs entry for @bitreverse
