X86InstrInfo.td updated: 1.249 -> 1.250
---
Log message:
* Allow mul, shl nodes to be codegen'd as LEA (if appropriate).
* Add patterns to handle GlobalAddress, ConstantPool, etc.
MOV32ri to materialize these nodes in registers.
ADD32ri to handle %reg + GA, etc.
MOV32mi to handle store GA, etc. to memory.
