Fused multiply-add support
Registered by
Michael Hope
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.
