Nicolai Haehnle ab43652716 [DAGCombine] require UnsafeFPMath for re-association of addition
Summary:
The affected transforms all implicitly use associativity of addition,
for which we usually require unsafe math to be enabled.

The "Aggressive" flag is only meant to convey information about the
performance of the fused ops relative to a fmul+fadd sequence.

Fixes Bug 31626.
