commit 52ab7604db35e0421bc3d2468a3af52b2c513a7b
Author: Noah Goldstein <goldstein.w.n@gmail.com>
Date: Fri Oct 14 22:00:25 2022 -0500
x86: Update VEC macros to complete API for evex/evex512 impls
1) Copy so that backport will be easier.
2) Make section only define if there is not a previous definition
3) Add `VEC_lo` definition for proper reg-width but in the
ymm/zmm0-15 range.
4) Add macros for accessing GPRs based on VEC_SIZE
This is to make it easier to do think like:
```
vpcmpb %VEC(0), %VEC(1), %k0
kmov{d|q} %k0, %{eax|rax}
test %{eax|rax}
```
It adds macro s.t any GPR can get the proper width with:
`V{upcase_GPR_name}`
and any mask insn can get the proper width with:
`{upcase_mask_insn_without_postfix}`
This commit does not change libc.so
Tested build on x86-64
