[AST] Use data-recursion when building ParentMap, avoid stack overflow.
The following crashes on my system before this patch, but not after:
void foo(int i) {
switch (i) {
case 1:
case 2:
... 100000 cases ...
;
}
}
clang-query -c="match stmt(hasAncestor(stmt()))" deep.c
I'm not sure it's actually a sane testcase to run though, it's pretty slow :-)
