Lynn Boger aff222cd18 cmd/compile: improve PPC64.rules to reduce size of rewritePPC64.go 
Some rules in PPC64.rules cause an extremely large rewritePPC64.go
file to be generated, due to rules with commutative operations and
many operands. This happens with the existing
rules for combining byte loads in little endian order, and
also happens with the pending change to do the same for bytes
in big endian order.

The change improves the existing rules and reduces the size of
the rewrite file by more than 60%. Once this change is merged,
then the pending change for big endian ordered rules will be
updated to use rules that avoid generating an excessively large
rewrite file.

This also includes a fix to a performance regression for
littleEndian.PutUint16 on ppc64le.
