[X86][BOLT] Use getOperandType to determine memory access size

Generate INSTRINFO_OPERAND_TYPE table in X86GenInstrInfo.inc.

This diff adds support for instructions that were previously reported as having
memory access size 0. It replaces the heuristic of looking at instruction
register width to determine memory access width by instead checking the memory
operand type using tablegen-provided tables.
