[InstCombine] Simplify binary op when only one operand is a select
Summary:
SimplifySelectsFeedingBinaryOp simplified binary ops when both operands
were selects with the same condition. This patch extends it to handle
these cases where only one operand is a select:
X op (C ? P : Q) -> C ? (X op P) : (X op Q)
// if X op P and X op Q both simplify
(C ? P : Q) op Y -> C ? (P op Y) : (Q op Y)
// if P op Y and Q op Y both simplify
For example: X *fast (C ? 1.0 : 0.0) -> C ? X : 0.0
