4ea2f441df Module: retry ZIR cache file creation 
There are no dir components, so you would think that this was
unreachable, however we have observed on macOS two processes racing to
do openat() with O_CREAT manifest in ENOENT.

87738cad86 wasm-linker: store symbol's virtual address 
For data symbols we will now store its virtual address. This means
we do no longer have to calculate it each time a relocation asks
for the address. This is now done for all data symbols only once
rather than every single relocation for that symbol.

This now also allows us directly store the virtual address of synthetic
symbols without having to create an atom for them. This means we also
don't need to have a "synthetic" segment any longer and do not emit
the synthetic symbols such as __heap_end and __heap_base into the final
binary.

ecc0108cea astgen: fill result location with void value if no other value 
With this change, `break` and `break :blk` will fill the result location
with `.void_value`, ensuring that the value will be type checked.
The same will happen for a for loop that contains no `break`s in it's body.

Closes https://github.com/ziglang/zig/issues/14686.

fea14c78d1 wasm-linker: emit build_id section (#14820) 
The Build ID is a value that uniquely identifies a build.

It is intended to capture the "meaning" or inputs of the build,
and is usually associated with debug info.

e3cf9d1650 Module: rewrite zir caching logic 
Multiple processes can sit waiting for the exclusive lock at the same
time, so we want to recheck whether it needs to be updated whenever
we get an exclusive lock.

This also fixes a race condition between one process truncating the
cache file and another process reading it without atomic locking.

70cbe5ac7c AstGen: remove unnecessary pubs 
I think it helps when you know that something is entirely
self-contained, which AstGen is. The only function public is `generate`.

6ab04b5941 std.os: Allow write functions to return INVAL errors 
In Linux when interacting with the virtual file system when writing
in invalid value to a file the OS will return errno 22 (INVAL).

Instead of triggering an unreachable, this change now returns a
newly introduced error.InvalidArgument.
