Updated GCM references to ISO
VideoConfigDiag: Updated video resolution description

Changed description to recommend selecting "auto"
Make expansion interface interrupt updates thread-safe (fixes loss of audio in Super Mario Sunshine on lower-end systems.)
JIT: micro-optimize cmpXX a bit more for lower latency/code size
JIT: use BLR optimization to avoid anding LR with 0xFFFFFFFC

Should save roughly one instruction per blr.
JIT: reorder blr comparisons

This should allow macro-op fusion in blr instructions.
JIT: optimize mulhwu
JIT: merge fcmpx and cror

Almost all uses of boolean condition-register ops in real code seem to be
the combination fcmpx + cror (e.g. for <= or >=). This merges the two.
JIT: optimize crclr special case of crxor
JIT: flush unused registers during branch merges

Also correct some flags in interpreter tables.
OGL: Use unique_ptr instead of pointer when taking screenshot.
BootManager: Get rid of unnecessary forward declaration
CheatSearchTab: Improve localization possibilities for a string

Numbers might not always be right-aligned for every language.
ConfigMain: Added missing filetypes to default ISO options
Fixed the endianess of the 32bit MMIO reads.
Reorganize faulting stuff.  Differentiate between arch- and OS-specific defines.

- Get rid of ArmMemTools.cpp and rename x64MemTools.cpp to MemTools.cpp.
  ArmMemTools was almost identical to the POSIX part of x64MemTools, and
  the two differences, (a) lack of sigaltstack, which I added to the
  latter recently, and (b) use of r10 to determine the fault address
  instead of info->si_addr (meaning it only works for specifically
  formatted JIT code), I don't think are necessary.  (Plus Android, see
  below.)

- Rename Core/PowerPC/JitCommon/JitBackpatch.h to Core/MachineContext.h.
  It doesn't contain anything JIT-specific anymore, and e.g. locking
  will want to use faulting support regardless of whether any JIT is in
  use.

- Get rid of different definitions of SContext for different
  architectures under __linux__, since this is POSIX.  The exception is
  of course Android being shitty; I moved the workaround definition from
  ArmMemTools.cpp to here.

- Get rid of #ifdefs around EMM::InstallExceptionHandler and just
  provide an empty implementation for unsupported systems (i.e.
  _M_GENERIC really).  Added const bool g_exception_handlers_supported
  for future use; currently exception handlers are only used by the JIT,
  whose use implies non-M_GENERIC, but locking will change that.

- Remove an unnecessary typedef.
Fix DSPLLE for games which DMA data from MEM2 to the DSP.

Fixes issue 7812.
GCPadEmu/WiimoteEmu: Make some arrays static
Interpreter: Remove a redundant macro
Merge pull request #1417 from fkane/threadsafe-interrupts

Defer processing of expansion interface interrupts (fixes audio in Super Mario Sunshine on lower-end systems)
