Hal Finkel 595817eebe Enable generating PPC pre-increment (r+imm) instructions by default. 
It seems that this no longer causes test suite failures on PPC64 (after r157159),
and often gives a performance benefit, so it can be enabled by default.

Hal Finkel 601f555eee Add a missing PPC 64-bit stwu pattern. 
This seems to fix the remaining compile-time failures on PPC64 when
compiling with -enable-ppc-preinc.
