28714ee75a general: Rename files with duplicate names
In MSVC, having files with identical filenames will result into massive slowdowns when compiling.
The approach I have taken to resolve this is renaming the identically named files in frontend/(A32, A64) to (a32, a64)_filename.cpp/h

7f77a04900 fuzz_arm: Do not test vfp_VMRS
This may emit a vmrs *, fpscr instruction.
This results in fuzz failures due to slight inaccuracies in fpscr emulation.

97277c598b A32: Rename vfp2-related files to vfp
Now that we fuzz against Unicorn, we aren't just restricted to VFPv2.
VFPv3 and VFPv4 facilities can now be implemented. This renames
constructs mentioning VFPv2 to just refer to VFP.

0b15fc9755 a32/fuzz_arm: Use same fuzzing mechanism as AArch64
Introduces the same fuzzing mechanism used by the AArch64 code for
fuzzing instruction implementations, getting rid of the need to
manually specify the instruction generator sequences--replacing it with
an instruction blacklist instead.

Much of this change originates from a previous patch made by Mary. This
just makes it interact nicely with the alterations made to get Unicorn
to cooperate properly.
