I suggest this be handled in the generic breakpoint-setting code, not
specific to "catch".  It's not a complete solution, by the way: it
will only help if the main executable uses catch / throw.  If only
shared libraries do, then there won't be a PLT entry in the
executable.  So maybe we should allow these breakpoints to be created
"pending"?
