e034422d2a ARM: Test r193381 a bit more thoroughly.
Make sure we're predicating right based on CPU even if the triple is 'wrong'.

3115047182 ARM: Tweak usage of '*vfp' compiler_rt functions.
Only use them if the subtarget has ARM mode, as these routines are implemented
as ARM code.

6c0138e5fc ARM: Use non-VFP softcalls on embedded Darwinish targets
The compiler-rt functions __adddf3vfp and so on exist purely to allow Thumb1
code to make use of VFP instructions by switching back to ARM mode, they make
no sense for M-class processors which don't even have an ARM mode.

Given that justification, in practice this is a platform ABI decision so the
actual check is based on that rather than CPU features.
