Jakob Stoklund Olesen 1083573796 Don't try to constant fold libm functions with non-finite arguments.
Usually we wouldn't do this anyway because llvm_fenv_testexcept would return an
exception, but we have seen some cases where neither errno nor fenv detect an
exception on arm-linux.

Dan Gohman 49c15c0f9f Attempt to XFAIL this test on arm-linux, which is inexplicably failing.

Dan Gohman 695312637c Fix this test so that folding doesn't depend on a potentially
"inexact" result.

Dan Gohman 18fa17cf3d 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.
