Re-commit: [ARM] CMSE code generation
This patch implements the final bits of CMSE code generation:
* emit special linker symbols
* restrict parameter passing to no use memory
* emit BXNS and BLXNS instructions for returns from non-secure entry
functions, and non-secure function calls, respectively
* emit code to save/restore secure floating-point state around calls
to non-secure functions
* emit code to save/restore non-secure floating-pointy state upon
entry to non-secure entry function, and return to non-secure state
* emit code to clobber registers not used for arguments and returns
* when switching to no-secure state
Patch by Momchil Velikov, Bradley Smith, Javed Absar, David Green,
possibly others.
