Preliminary support for ARM frame save directives emission via MI flags.
...
This is just very first approximation how the stuff should be done
(e.g. ARM-only for now). More to follow.

Each prologue may have multiple vpush instructions to store callee-saved
...
D registers since the vpush list may not have gaps. Make sure the stack
adjustment instruction isn't moved between them. Ditto for vpop in
epilogues.
Sorry, can't reduce a small test case.
