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
