Sanjay Patel b57d0a2fda [TargetLowering] remove fdiv and frem from canOpTrap() (PR29114) 
Assuming the default FP env, we should not treat fdiv and frem any differently in terms of 
trapping behavior than any other FP op. Ie, FP ops do not trap with the default FP env.

This matches how we treat these ops in IR with isSafeToSpeculativelyExecute(). There's a 
similar bug in Constant::canTrap().

This bug manifests in PR29114:
https://llvm.org/bugs/show_bug.cgi?id=29114
...as a sequence of scalar divisions instead of a vector division on x86 for a <3 x float> 
type.
