Make ceil/floor/nearbyint/rint/round const even with -fmath-errno. The conditions described by POSIX can never happen with IEEE-754 floats. When the function is const we can emit a single sse4.1 instruction for it, without losing anything :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162379 91177308-0d34-0410-b5e6-96231b3b80d8
