Qiu Chaofan a4c5351986 [DAGCombiner] Propagate FMF flags in FMA folding
DAG combiner folds (fma a 1.0 b) into (fadd a b) but the flag isn't
propagated into new fadd. This patch fixes that.

Some code in visitFMA is redundant and such support for vector constants
is missing. Need follow-up patch to clean.
