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.

unittests/ASM: Adds SIB transpose scale register test 
With a bit of pointer math it will choose the incorrect address if the
base and offset registers were transposed.

InstCountCI: Adds SSE4.2 operations 
Doesn't handle all 127 combinations of the control immediate for all
four instructions. Although supplies the instruction control instruction
that A Hat in Time abuses heavily.

The SSE2 implementation of the function in vcruntime140 is likely faster
than our currently implementation but we should be able to get something
comparable. Not bad considering this is a required extension and this is
the first game we found that abuses the instruction heavily.

alternative to #3638. this is theoretically better for side-by-side diffs. in
practice it may make other diffs worse since all the \'s change when part of the
macro change.

OpcodeDispatcher: Implement support for SMSW 
Found out that Far Cry uses this instruction and it is viable to use in
CPL-3. This only returns constant data but its behaviour is a little
quirky.

This instruction has a weird behaviour that the 32-bit operation does an
insert in to the 64-bit destination, which might be an Intel versus AMD
behaviour. I don't have an Intel machine available to test if that
theory is true although. This assumption would match similar behaviour
where segment registers are inserted instead of zext.

Gets the game farther but then it crashes in a `___ascii_strnicmp`
function where the arguments end up being `___ascii_strnicmp(nullptr, "Color", 5);`.
