Note, the patch will fix the errors in compiling pr27158.c and altivec-spat.c.
It will not fix the errors in compiling unonbon.c, which is an entirely
different problem.

Note, the fix proposed in PR64151 DOES NOT work on the PowerPC, so it may be a
dup in terms of what change broke the build, but the potential fix needs more
analysis.

Ah, ok, it helps to read the bug report. If you bootstrap with --with-cpu=G5
it fails, --with-cpu=power5 passes.

I put a LP64 on the test, because it was using 64-bit shifts in order to force
registers to be allocated from the Altivec register set. If you compile it in

My gut feeling is we don't want to change ?m to !m, because it might impact
floating point conversions - integer, where we need the DI mode in a floating
