Improve performance and configurability for the StructReturn pass.
configure: special ABI value for IA32/MacOSX and PowerPC/Linux
cparser/Machine: special config for PowerPC/Linux
cparser/StructReturn: generate better code for return-as-int
driver/Clflags, driver/Driver: add options -fstruct-return=<convention>
and -fstruct-passing=<convention> to simplify testing
