YJIT: Print exit reasons on failure in test_yjit.rb
...
For <https://bugs.ruby-lang.org/issues/19921 >, I suspect the test is
failing due to a timing related interrupt, which on paper could
happen with slow-enough GC runs.
In any case, it's helpful for debugging to have more information when
tests fail.

YJIT: Fix raw sample stack lengths in exit traces ( #7728 )
...
yjit-trace-exits appends a synthetic sample for the instruction being
exited, but we didn't increment the size of the stack. Fixing this count
correctly lets us successfully generate a flamegraph from the exits.
I also replaced the line number for instructions with 0, as I don't
think the previous value had meaning.

YJIT: Fix edge and total counts in exit_locations ( #7702 )
...
The stackprof-format raw samples are suffixed with a count (ie. how many
times did the previously recorded side-exit repeat). Previously we were
correctly using this value to increment the :samples count, but not the
:total_samples count or edges.
This made the stackprof aggregate results incorrect (though any
flamegraphs generated should have been correct, since those only rely on
raw samples).
