This adds a separate file for the fp denormal regression tests. NFC. I forgot to svn add the new file in my previous commit. llvm-svn: 283110

// RUN: %clang -### -target arm-unknown-linux-gnu -c %s -fdenormal-fp-math=ieee -v 2>&1 | FileCheck -check-prefix=CHECK-IEEE %s
// RUN: %clang -### -target arm-unknown-linux-gnu -c %s -fdenormal-fp-math=preserve-sign -v 2>&1 | FileCheck -check-prefix=CHECK-PS %s

Guard flag –fdenormal-fp-math with –fno-fast-math. This allows disabling the FP options with just one flag (-fno-fast-math). Differential Revision: https://reviews.llvm.org/D25479 llvm-svn: 284121
