Proposed patch

This patch adds the FMA patterns and aligns the SH target with the -mfused-madd
/ -mno-fused-madd option handling in other targets.

Kaz, if you have some time and a SH64 test env at hand, could you please check
the patch on SH64?
I had to touch the __builtin_sh_media_FMAC_S mapping.  I think it should be OK,
since the number and semantics of the insn operands is the same as before.
