Alyssa Rosenzweig aa7dcffcea ConstProp: drop const pool heuristic 
slightly worse for compile time, slightly better output, honestly I'll take the
win because this is easier to reason about.

No reason to have a separate pass for this, merging should be a bit faster since
it eliminates an IR walk.

FEXLoader: Cleanup FD extraction from environment variables
 2024-05-29 19:18:59 -07:00
Ryan Houdek 3b5d0e3e27 FEXLoader: Cleanup FD extraction from environment variables 
In preparation for seccomp execve inheritance where we need to extract
another FD from a different environment variable.

- Small function to extract the FD and also unset the environment
  variable in the same place.
   - Keeping the fetch and unset together instead of spreading to
     another location in the source.
- Extract the FD upfront instead of passing the string_view around,
  since we are unsetting the environment variable at the same place.

Future seccomp inheritance will get the FD just after the FEXFD
   - `int FEXSeccompFD {GetFEXFDFromEnv("FEX_SECCOMPFD")};`

Ryan Houdek 37e13cf073 FileManagement: Fix fstatat with self and NOFOLLOW 
When asked to not follow the symlink, FEX needs to return data about the
symlink itself rather than following to the target executable. In that
case we need to return symlink information otherwise games that sanity
check can break.

This is what happened with Darwinia in #3662.

We return the FEXInterpreter symlink information in this case since it
doesn't return any information that is relevent to leaking emulator
state. Once the application asks to follow through to the symlink target
is when we will replace.

Also adds a unit test to ensure we don't break it.
