gcc15.2 docs list the sanitizers that support recovery, and "leak" is not in
that list. Sanitizers that support it enable recovery by default, except for
"address", which is noted as still being experimental (which is presumably why
it's not enabled by default).
https://gcc.gnu.org/onlinedocs/gcc-15.2.0/gcc/Instrumentation-Options.html#index-fsanitize-recover
Once "address" is no longer experimental we can presumably remove the explicit
recovery enabling.

But maybe we should consider this PR premature, since `-fsanitize-recovery=address" is still experimental.
