New library (final_simd.h)

[f1nalspace]

I want a library that abstracts/wrap the internal SIMD types such as __m128 to structs and uses better names for the actual functions. Also, this should work on X86/X64 and ARM.

On NEON the names for the typedefs are much better than on x86, so we use those instead ;)

__m128 becomes fsmd_f32x4
__m128d becomes fsmd_f64x4
__m128i becomes fsmd_s32x4
__m256 becomes fsmd_f32x8

Example function names:

_mm256_fmadd_ps:

fsMultiplyAdd256F(const fsmd_f32x8 a, const fsmd_f32x8 b, fsmd_f32x8 *output)
