Austin Clements 6f22d42c74 runtime: resolve caller funcInfo after processing current frame
Currently, gentraceback resolves the funcInfo of the caller prior to
processing the current frame (calling the callback, printing it, etc).
As a result, if this lookup fails in a verbose context, it will print
the failure before printing the frame that it's already resolved.

To fix this, move the resolution of LR to a funcInfo to after current
frame processing.

This also has the advantage that we can reduce the scope of "flr" (the
caller's funcInfo) to only the post-frame part of the loop, which will
make it easier to stack-rip gentraceback into an iterator.

For #54466.
