36da3000c0 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.

80be5e4832 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.

8796da0283 dwarf: reuse getDbgInfoAtom helper in all of Dwarf.zig
We need to access it outside of `DeclState` too so why not reuse
the helper anyway.

7d3cc3bc8d 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.

4aae0b09cf CBE and LLVM: handle unused try instructions
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.

3a9375cae9 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.

29e8e67a7e 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.
