--- Comment #1 from Hal Finkel <hfinkel at anl.gov> ---
r246937, thanks! As it turns out, the bug was not in SelectBitfieldInsert, but
in the code that tried to later commute the operands of the resulting rlwimi
instruction.

This also points out an underlying code-quality issue (there's no need for the
trivial rlwimi instructions in the first place), and I'll investigate fixing
that too.
