Renato Golin a4d563526e Fix Darwin NEON FP and increase coverage 
llvm-svn: 177664

Renato Golin b4dd6c5945 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.

Jim Grosbach 71fcb4fedd switch the flag for using NEON for SP floating point to a subtarget 'feature'. 
Re-commit. This time complete with testsuite updates.
