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.
DiscIO: Simplify GetUniqueID in VolumeDirectory
DiscIO: Get rid of some casts and a c_str call in VolumeDirectory
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.
Fix warnings.
X64Emitter: support shorter mov reg, imm opcodes

Also refactor WriteNormalOp a little bit and add comments.
Move "using namespace ArmGen" from headers to sources.
include CommonTypes.h instead of Common.h, remove unused using.

Fix warnings.
JIT: unify subfe/submex/subfex/adde/addmex/addzex code

Shorter, plus should make future optimizations easier.
JIT: unify subfcx and addcx code

Again, shorter and should make future optimizations easier.
Fix AArch64 MOVI2R helper function.
In the case of a zero immediate, it wouldn't generate code at all.
Also in the case of max u32/u64, use ORN to optimize it.
Fix all the current issues with the AArch64 register cache.
Fixes all the current issues I've been experiencing.
Scaled back the register cache idea for now so I can actually work on some real instructions.

Tested this work with unit tests so I know it works.
Unit tests are pretty great things.
DiscIO: Remove unnecessary break statements.
DolphinWX: Get rid of fallthrough in ScanForISOs
CBoot: Use vectors instead of raw pointers in ELF functions.
