On bug_10107.v: - before this PR 0.037s - after this PR 0.043s - enable Ltac2 Backtrace 0.2s - enable Ltac Profiling 3s - without compiling 0.25s - Ltac2 Backtrace without compiling 1s - Ltac Profiling without compiling 30s Note that this implementation only puts the FrLtac frames, not the ones of anon functions. This is especially impactful for recursion as `Ltac2 rec bla binders := ...` becomes `Ltac2 bla binders := let rec bla binders := ... in bla binders` so only the top call gets a frame, and with profiling only the top call produces overhead. We should expect that adding frames for anonymous functions / recursive calls would be significantly worse than the current results.
