776208742b emit_x64_{vector_}floating_point: Centralize implementation of FP{Vector}{Abs,Neg} 
Removes dependency on the constants at the top of some files
such as `f16_negative_zero` and `f32_non_sign_mask` in favor
of the `FPInfo` trait-type.

Also removes bypass delays by selecting between instructions
such as `pand`, `andps`, or `andpd` depending on the type
and keeps them in their respective uop domain.

See https://www.agner.org/optimize/instruction_tables.pdf for
more info on bypass delays.

c157dfcc4c emit_x64_vector: Reduce gf2p8affineqb requirement to GFNI 
Currently, every usage of `gf2p8affineqb` is guarded by the
`AVX512F + AVX512VL + GFNI` requirement, when really
we only need `GFNI` on its own.

This will allow `GFNI`-only chips to get emit GFNI features without
needing to have AVX512 as well.
There _are_ chips in existance currently that strictly ship with GFNI and
have no implementation of AVX1/AVX2/AVX512(and thus no VEX/EVEX
encoding) such as Tremont(Lakefield) chips.

0c12614d1a A64/config.h: Split fastmem and page_table options. 
We might want to allocate different sizes for each of them.
e.g. for the unsafe fastmem approach without bounds checking.
Or for using the full 48bit adress range (with mirrors) by allocating our real arena as close to 1<<47 as possible.

ff01b1c6f9 a64/fastmem: Only generate abort handler if needed. 
If fastmem fails, we call the callback from the signal handler. So this callback proxy in slowmem won't be used ever.

fa8cc1ac36 backend/x64: Add constants 
Used to redefine x86 assembly-constants without
including platform-dependent headers such as `immintrin.h`.

Currently includes vpcmp constants as well as ternary logic
utility-terms.

Removes `immintrin.h` requirement from emit_x64_vector_saturation
and updates our usage of `vpcmp` and `vpternlog` with the new constants
