[SimplifyCFG] Remove conservative fcmp guard from speculativelyExecuteBB

Previously it rejected to perform if conversion when the condition was
an FCmpInst. That guard predated the current cost model which now takes
into consideration target-dependent knobs such as getCmpSelInstrCost()
via validateAndCostRequiredSelects.

Also propagate fast-math flags from the phi to the replacement select using
CreateSelectFMF instead of CreateSelect.
