[PATCH] D109153: [ARM][CMSE] Clear the secure fp-registers when using softfp abi.

[Momchil Velikov via Phabricator via llvm-commits]

chill added a comment.

Looks reasonable. Could we, please, add a comment which explains why it's correct to emit `vlldm/vllsm` (e.g. "they behave as NOPs") and various other instrucvtion that access FP regfisters (e.g. "we are passing parameters in FP-regs anyway")?
