> We hit an assert while printing nmethod entry point labels when attempting to create a symbol from the `SigEntry` to iterate over. The problem is that we are holding the tty lock and symbol creation also acquires certain locks. I've refactored the code to completely avoid symbol creation and also fixed an issue where names of reference argument types are not printed anymore (because we don't keep track of that in `SigEntry`). I've also removed lots of dead code leftovers from old reserved entry support in the calling convention.
