[X86][SLH] Regroup the instructions in isDataInvariantLoad a little. NFC
-Move BSF/BSR to the same group as TZCNT/LZCNT/POPCNT.
-Split some of the bit manipulation instructions away from TZCNT/LZCNT/POPCNT. These are things like 'x & (x - 1)' which are composed of a few simple arithmetic operations. These aren't nearly as complicated/surprising as counting bits.
-Move BEXTR/BZHI into their own group. They aren't like a simple arithmethic op or the bit manipulation instructions. They're more like a shift+and.
