Description David Degazio 2022-12-01 16:41:35 PST

We should add support for SIMD bitwise logic, shift, and boolean operations on Intel. This means support for the following instructions:

 - i8x16.shl, i16x8.shl, i32x4.shl, i64x2.shl
 - i8x16.shr_s, i16x8.shr_s, i32x4.shr_s, i64x2.shr_s, i8x16.shr_u, i16x8.shr_u, i32x4.shr_u, i64x2.shr_u
 - v128.and
 - v128.or
 - v128.xor
 - v128.andnot
 - v128.bitselect
 - i8x16.popcnt
 - v128.any_true
 - i8x16.all_true, i16x8.all_true, i32x4.all_true, i64x2.all_true
