gccrs: macro-expand: Keep optional references to last_{def, invoc}
This avoids a use-after-free when reaching the recursion limit.
gcc/rust/ChangeLog:
* expand/rust-macro-expand.h: Keep optional references for last_def
and last_invoc.
* expand/rust-macro-expand.cc (MacroExpander::expand_invoc): Store
optional references.
* rust-session-manager.cc (Session::expansion): Use tl::optional's APIs
for better checking.
