CLI: quality of life enhancement for windows CBE behavior tests
...
When testing with
```
stage4/bin/zig test ../test/behavior.zig -I../test -ofmt=c -target x86_64-windows
```
previously, one would see this message:
```
error: lld-link: subsystem must be defined
```
Now, `--subsystem console` as well as `-lntdll -lkernel32` are on the
`zig run` line, producing a binary.

Sema: resolve elem type for non-default aligned ptrs
...
Before this commit, I observe a crash from this abiSize call because the
element type is a struct that is not yet resolved. This is triggered by
running the behavior tests with -ofmt=c -target x86_64-windows.

zig cc: fix wrong flag name from earlier commit
...
In dfe942024461a3598fc872ea79e7859a8744b550, I made a typo. This commit
corrects it. I tested this commit via a patch to zig-bootstrap.

wasi-libc: define BULK_MEMORY_THRESHOLD for the bulk_memory feature ( #13787 )
...
When the bulk_memory feature is enabled, wasi-libc will only use
it if the number of bytes is >= BULK_MEMORY_THRESHOLD
Set it to 32 as in the original wasi-libc Makefile.

CBE: defer invariant local reuse in loops
...
When a local defined outside a loop dies inside the loop, it can still
be needed on subsequent loop iterations, so reuse of the local must be
deferred until after the loop ends. This causes behavior tests to pass.

In both backends they did not observe the Liveness information for try
instructions. Now they do. For the C backend this is necessary for
correctness; for the LLVM backend, it improves code generation.

wasm codegen: fix some missing Liveness reaps
...
I did not do a full audit, but I did notice a few issues which are
resolved in this commit. Probably it would be worth adding debug
infrastructure to assert that the number of reaps equals the number of
calls to resolveInst() per air lowering function.

CBE: use bool, true, false, instead of zig_ prefixes
...
In general the C backend should lower to human-maintainable C code
whenever possible. Directly using C types that one would use when
writing C code is one part of the strategy.
The concern with including stdint.h is C89 compatibility. Well, we can
just check the C std lib version before deciding to include that header.
