I could have sworn I sent this patch out in mid-December, but I don't see it,
so I'm resending this now.
This patch fixes the problem that breaks some code on the SPE. I have patches
for 4.8 and 4.9. Roland says that it fixes the problem in 4.8. In 4.9 there
are other unrelated problems that Roland is currently working on.
I tested these patches on powerpc linux, and I did not see a regression. Are
these patches ok to check into both the 4.8 and 4.9 branches?

* config/rs6000/rs6000.c (rs6000_legitimate_offset_address_p):
Only check TFmode for SPE constants. Don't check TImode or
TDmode.
