Update tests. llvm-svn: 85050

; RUN: llc < %s -march=arm -mattr=+vfp2 | FileCheck %s -check-prefix=VFP2
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

; RUN: llc < %s -march=arm -mattr=+neon | FileCheck %s -check-prefix=NEON
; RUN: llc < %s -march=arm -mcpu=cortex-a8 | FileCheck %s -check-prefix=NEONFP
Initial support for single-precision FP using NEON. Added "neonfp" attribute to enable. Added patterns for some binary FP operations. llvm-svn: 78081

vml[as].f32 cause stalls in following advanced SIMD instructions. Avoid using them for scalar floating point operations for now. llvm-svn: 85697
