Merge #337
337: Fix unwinding through `Reset` r=thejpster a=jonas-schievink
Unwinders may detect the end of the program by seeing `0xFFFFFFFF` in `lr`, which is why code to ensure that it has that value was added in https://github.com/rust-embedded/cortex-m-rt/pull/293. However, the `bl main` overwrites that value with the current program counter. This PR saves the old `lr` value on the stack, and adds debuginfo entries to allow an external unwinder to restore the value.
This fixes https://github.com/knurling-rs/probe-run/issues/277
