Rollup merge of #32437 - eddyb:orbital-msvc, r=alexcrichton

Annotate run-pass/backtrace with #[rustc_no_mir] on MSVC.

Fixes #32384 by not using MIR on MSVC for the functions in the path of the backtrace.
This is the known blocker for the MSVC MIR builder, hopefully the only one overall.
r? @alexcrichton Confirmed to work on a nightly, by @retep998.
