was returning incorrect values in rare cases, and incorrectly marking exact conversions as inexact in some more common cases. Fixes PR11406, and a missed optimization in test/CodeGen/X86/fp-stack-O0.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145141 91177308-0d34-0410-b5e6-96231b3b80d8
