* Added lowering hook for external weak global address. It inserts a load
...
for Darwin.
* Added lowering hook for ISD::RET. It inserts CopyToRegs for the return
value (or store / fld / copy to ST(0) for floating point value). This
eliminate the need to write C++ code to handle RET with variable number
of operands.
