181f16c5f0 Reimplements fastmem for ARMv7 floating point loadstores. 
This implements a new system for fastmem backpatching on ARMv7 that is less of a mindfsck to deal with.
This also implements stfs under the default loadstore path as well, not sure why it was by itself in the first place.

I'll be moving the rest of the loadstore methods over to this new way in a few days.

b0becf7af8 Enables the ARMv7 FPR cache. 
The problem instructions with the FPR are disabled in the previous commit. This can now be reenabled for fairly large performance gains.

69c3e6516c Disables NEON optimized instructions. 
These are causing issues in games. In particular you get pink on the screen in Animal Crossing.
Disable until fully investigated.

This also disables fastmem on floating point loadstore instructions which are horribly broken and won't actually backpatch when an invalid read/write
is encountered.

ce71c3cd4e JIT: fix valid_block marking 
This caused invalidations that only affected the last portion of a JIT block

games too; I haven't tested.

7deaf00c44 JIT: more mftb fixes 
A very subtle difference in how I calculated the timebase value seems
to have broken Karaoke Revolution; this seems to fix it. Also be a bit more
paranoid in conditions for mftb merging.

2ecd849eab 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.
