Fused multiply-add support

Registered by Michael Hope on 2012-09-11

VFVv4 adds a fused multiply-add instruction along with a few different variants. Matt added support upstream in r189283, but the testsuite fails on our Thumb-2+hardfloat configuration.

Also pull in Ramana's support for NEON FMA.

Fix up the testsuite upstream, backport the FMA patch, backport the testsuite.
