* 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.

exposed with a fastcc problem (breaking pcompress2 on x86 with -enable-x86-fastcc).
When reloading a reused reg, make sure to invalidate the reloaded reg, and
check to see if there are any other pending uses of the same register.
