Sanjay Patel 21c15ef384 [Reassociate] try harder to convert negative FP constants to positive 
This is an extension of a transform that tries to produce positive floating-point
constants to improve canonicalization (and hopefully lead to more reassociation
and CSE).

The original patches were:
D4904
D5363 (rL221721)

But as the test diffs show, these were limited to basic patterns by walking from
an instruction to its single user rather than recursively moving up the def-use
sequence. No fast-math is required here because we're only rearranging implicit
FP negations in intermediate ops.

A motivating bug is:
