NAKAMURA Takumi b4eef1fa4a llvm/test/Transforms/DCE/calls-errno.ll: Suppress checking @pow(+0,-1).
It depends on host's pow(3), and mingw's pow doesn't raise any errors, just returns +INF.

Eli Friedman b6befc3bc4 DCE math library calls with a constant operand.
On platforms which use -fmath-errno, math libcalls without any uses
require some extra checks to figure out if they are actually dead.

Fixes https://llvm.org/bugs/show_bug.cgi?id=30464 .
