Fix bug in Load Paired so JitIL actually runs again.

Was broken in the PowerPCState Register PR a few days ago.
JitIL: Fix matching bug in Store Paired.

Most non-wii, non-mmu games run now.
Gameini cleanup.

This is a cleanup of the gameini database. Specifically:
It removes the "Issues=..." lines and their respective comments since
they don't show up in the gui, are very old and wrong in most cases.
They contain probably more than 4 year old comments (i don't have a clue
who or when wrote them).
Also remove the "EFBCopyCacheEnable = True" lines from the database.
These were put at a time that efb to Ram had resolution issues without
cache being enabled, safe texture cache could be disabled and speed was
detrimental. Now that efb to ram doesn't have the same res issues as
back then, safe texture cache can't be disabled with speed gains being
non existent (you get even a speed hit if texture cache is put to safe)
i think it should be removed from the database.

Include a missing include in the ARM emitter's common code.
Fix the return value of PPCAnalyst.
In situations where conditional continue isn't supported + if a JIT doesn't implement a instruction that has the FL_ENDBLOCK flag. This would cause an
infinite loop.
In reality all the JITs should implement every FL_ENDBLOCK instruction regardless, but JITIL doesn't implement tw/twi which are FL_ENDBLOCK
instructions.
JIT: use XCHG in MOVTwo

Roughly the same speed or slightly faster depending on CPU; mostly just cleaner
since we don't have to pass in a temp.
