Ensure stack before parsing dot-or-call #122717

There are many cases where, due to codegen or a massively unruly codebase, a deeply nested call(call(call(call(call(call(call(call(call(f()))))))))) can happen. This is a spot where it would be good to grow our stack, so that we can survive to tell the programmer their code is dubiously written.

Closes #122715
