pstef 2e868fc00b Pop fast-math at the end of the file 
so that it doesn't affect the rest of the code in Griffin builds.

This is unfortunately GCC-only, but Clang will miss only 1 vectorization.

pstef 6bfb7862e7 Make -ffast-math exclusive to sinc_resampler.c 
-ffast-math was added in ff14092d8d with a comment that it "helps SINC
resampler to auto-vectorize". The flag is an alias for "-fno-math-errno
-funsafe-math-optimizations -ffp-contract=fast -fno-honor-infinities
-fno-honor-nans". The last two of those cause compiler complaints
because while the flag was meant for this file, it's shared across the
codebase that includes statements that operate on infinities and NaNs.

GCC 13.3 with -fopt-info-vec reports 18 vectorizations for `-O3
-ffast-math`, 17 for `-O3 -fno-math-errno -funsafe-math-optimizations
-ffp-contract=fast` and also 17 for plain `-O3`. So using the subset of
-ffast-math without the offending flags buys nothing and loses 1
vectorization.

Both GCC and Clang provide the "fast-math" pragma directive, which I add
to this one file that benefits from it, under the condition that it's
supported. -ffast-math is removed from most of the makefiles.

LibretroAdmin a974cef001 (sinc resampler) Simplifications - call besseli0 directly instead of 
through kaiser_window_function wrapper function - get rid of some unnecessary
sqrtf calls and such, some other small opts

Add intrinsic NEON versions for float_to_s16/s16_to_float (#12933) 
* Add intrinsic NEON versions for float_to_s16/s16_to_float courtesy
of davidgfnet

* Define -DDONT_WANT_ARM_OPTIMIZATIONS for resampler sinc - this should
default to intrinsic versions

* Default to ARM NEON intrinsic codepath and make the ASM codepaths
optional by defining HAVE_ARM_NEON_ASM_OPTIMIZATIONS

* (Pkg/apple/Android) Take out ASM files being compiled in
