ART: Address three issues with x86 assembler before enabling load store elimination.

1) Remove the IS_LOAD attribute from LEA instructions.
2) Change the attribute of fp stack instructions from IS_UNARY_OP to IS_BINARY_OP as
   operands[1] will be used to compute GetInstructionOffset.
3) Add IS_MOVE attribute for general register move instructions.
