Huihui Zhang 9cd7c534e2 [InstCombine] Enable fold select into operand for FAdd, FMul, FSub and FDiv. 
For FAdd, FMul, FSub and FDiv, fold select into one of the operands to enable
further optimizations, i.e., floating-point reduction detection.

Turn code:
  %C = fadd %A, %B
  %D = select %cond, %C, %A

into:
  %C = select %cond, %B, -0.000000e+00
  %D = fadd %A, %C

Alive2 verification (with --disable-undef-input), timed out otherwise.
