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.

bdb6fb5763 CI: use cache directories local to the CI run
Override the cache directories because they won't actually help other CI
runs which will be testing alternate versions of zig, and ultimately
would just fill up space on the hard drive for no reason.

In practice we did see one of the CI servers fill up too many files
inside ~/.cache/zig, which caused certain file system operations to
start returning ENOSPC, despite the hard drive having plenty of space
left.

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.

e2509ddbe6 AstGen: add error for invalid string comparisons
These operations are allowed because the string literals are just
pointers but they produce unexpected results. These errors prevent
beginners from shooting themselves in the foot while still allowing
advanced users to circumvent them if they desire to do so.
