Merge #467
467: cortex-m-rt: Remove LR push, to ensure the stack is 8-byte aligned. r=adamgreig a=Dirbaio
This was causing incorrect execution of code optimized with the assumption the stack is 8-byte aligned.
Alternate version of #463
- Remove instead of fix the sentinel/fake frame.
- Remove code initializing LR, since it's now clobbered by the `bl main` anyway.
- ~~Remove the .cfi directives, since Reset now has no correct CFI info. I think this is the "correct" thing to do here.~~
- ~~Initialize the frame pointer in R7 (suggestion from `@jamesmunns)~~`
