Fix the folding of floating-point math library calls, like sin(infinity), so that it detects errors on platforms where libm doesn't set errno. It's still subject to host libm details though. llvm-svn: 114148

; RUN: opt -instcombine -S < %s | FileCheck %s
; This shouldn't fold, because sin(inf) is invalid.
; CHECK: @foo
; CHECK: %t = call double @sin(double 0x7FF0000000000000)
define double @foo() {
%t = call double @sin(double 0x7FF0000000000000)
ret double %t
}
; This should fold.
; CHECK: @bar
Fix this test so that folding doesn't depend on a potentially "inexact" result. llvm-svn: 114198
