As the -fsanitize-recover option comes from clang originally, I think
this needs coordination with them (whether clang will also rename the
option), and certainly keep -fsanitize-recover as a non-documented
compat option alias for -fubsan-recover.
So, can you please talk to the clang folks about it?
