macros: Do not try and re-expand if depth has exceeded recursion limit
We need to limit the amount of times that macro get expanded recursively
during macro-expansion. This limits the amount of times an ASTFragment
can be visited by simply incrementing the depth when setting a fragment,
and decreasing it when taking one. This way, recursive expansion which
happens at the expansion level (instead of the matching level) will
still get caught
