529916ca4a Add some missing isel predicates on def : pat patterns to avoid generating VFP vmla / vmls (they cause stalls). Disabling them in isel is properly not a right solution, I'll look into a proper solution next.

7ec7a0e96b switch the flag for using NEON for SP floating point to a subtarget 'feature'.
Re-commit. This time complete with testsuite updates.

8cd0a8cb82 vml[as].f32 cause stalls in following advanced SIMD instructions. Avoid using
them for scalar floating point operations for now.

9843a93e83 Remove neonfp attribute and instead set default based on CPU string. Add -arm-use-neon-fp to override the default.
