switch the flag for using NEON for SP floating point to a subtarget 'feature'. Re-commit. This time complete with testsuite updates. llvm-svn: 99570

Initial support for single-precision FP using NEON. Added "neonfp" attribute to enable. Added patterns for some binary FP operations. llvm-svn: 78081

Add LLVM support for Swift. llvm-svn: 164899

Avoid NEON SP-FP unless unsafe-math or Darwin NEON is not IEEE 754 compliant, so we should avoid lowering single-precision floating point operations with NEON unless unsafe-math is turned on. The equivalent VFP instructions are IEEE 754 compliant, but in some cores they're much slower, so some archs/OSs might still request it to be on by default, such as Swift and Darwin. llvm-svn: 177651
