Get rid of infinite recursion for 'typedef' used with GTY-marked 'gcc/diagnostic-spec.h:nowarn_map' [PR101204, PR103157]
Reproduced with clang version 10.0.0-4ubuntu1:
gtype-desc.c:11333:1: warning: all paths through this function will call itself [-Winfinite-recursion]
... as well as some GCC's '-O2 -fdump-tree-optimized':
void gt_pch_nx(int_hash<unsigned int, 0u, 4294967295u>*, gt_pointer_operator, void*) ([...])
{
<bb 2>:
<bb 3>:
goto <bb 3>;
}
That three-arguments 'gt_pch_nx' function as well as two one-argument
'gt_ggc_mx', 'gt_pch_nx' functions now turn empty:
[...]

-gt_ggc_mx (int_hash<location_t,0,UINT_MAX>& x_r ATTRIBUTE_UNUSED)
+gt_ggc_mx (struct xint_hash_t& x_r ATTRIBUTE_UNUSED)
{
- int_hash<location_t,0,UINT_MAX> * ATTRIBUTE_UNUSED x = &x_r;
- gt_ggc_mx (&((*x)));

}

}
