Operand types of 64-bit LEA instructions (x86-64)

Hi all,

I’ve noticed that operand type of mem operands of 64-bit LEA instructions on x86-64 (lea64_mem and lea64_32mem in X86InstrInfo.td) is not set. It is set to ‘OPERAND_MEMORY’ for mem operands of all other instructions.

Is there a reason for this? It looks like an omission to me and setting it to ‘OPERAND_MEMORY’ does not break any tests, but I wanted to double-check before sending a patch.
