a833bdcd7e [ld] add --print-* for diagnostics 
This adds the following for passthrough to lld:
- `--print-gc-sections`
- `--print-icf-sections`
- `--print-map`

I am not adding these to the cache manifest, since it does not change
the produced artifacts.

Tested with an example from #11398: it successfully prints the resulting
map and the GC'd sections.

8378cde743 macho: prefill any space between __DATA and __LINKEDIT with 0s if required 
If there are zerofill sections, the loader may copy the contents of
the physical space in file directly into memory and attach that to
the zerofill section. This is a performance optimisation in the loader
but requires us, the linker, to properly zero-out any space between
__DATA and __LINKEDIT segments in file. This is of course completely
skipped if there are no zerofill sections present.

0ae2ea671b wasm: temporarily save curr file pointer before pwriting on Win 
This is a temporary workaround to an unclear platform-dependence
behavior we have in libstd for `std.fs.File` abstraction. See
https://github.com/ziglang/zig/issues/12783 for more information.

99826a2ba8 Sema: fix UAF in zirClosureGet 
Previously if a decl failed its capture scope would be deallocated and
set to undefined which would then lead to invalid dereference in
`zirClosureGet`. To avoid this set the capture scope to a special
failed state and fail the current decl with dependency failure if
the failed state is encountered in `zirClosureGet`.

e0167ae0e3 x86_64: allow for any index register in complex SIB encodings 
This relieves register pressure, and reduce generated code size
(since now we can use the same index register for both `mov_scale_src`
and `mov_scale_dst` MIR instructions).

Fix lowering of ModRM + SIB encodings where index register is extended
- previously, we would carelessly ignore the fact generating incorrect
encodings.
