Jinsong Ji 4d8c0e830b [DAGCombine] reassoc flag shouldn't enable contract 
According to IR LangRef, the FMF flag:

contract
Allow floating-point contraction (e.g. fusing a multiply followed by an
addition into a fused multiply-and-add).

reassoc
Allow reassociation transformations for floating-point instructions.
This may dramatically change results in floating-point.

My understanding is that these two flags shouldn't imply each other,
as we might have a SDNode that can be reassociated with others, but
not contractble.

eg: We may want following fmul/fad/fsub to freely reassoc, but don't
want fma being generated here.

   %F = fmul reassoc double %A, %B         ; <double> [#uses=1]
   %G = fmul reassoc double %C, %D         ; <double> [#uses=1]
   %H = fadd reassoc double %F, %G         ; <double> [#uses=1]
   %I = fsub reassoc double %H, %E         ; <double> [#uses=1]

Before https://reviews.llvm.org/D45710, `reassoc` flag actually
did not imply isContratable either.

The current implementation also only check the flag in fadd node,
ignoring fmul node, this patch update that as well.
