Factor out the check for a variable that's still repeating.
Identify metavariable functions by using named symbols rather than string comparisons.

@hkBst I don't think anything in the perf suite is likely to test metavariable expressions. |

(Also, feel free to review and merge, I don't think this needs to wait for petrochenkov specifically.) |

…r=petrochenkov mbe: Simplifications and refactoring A few simplifications and refactors in advance of other work. Macro metavariable expressions were using `Ident::as_str` and doing string comparisons; I converted them to use symbols. I factored out a function for transcribing a `ParseNtResult`, which will help separate the evaluation and transcription of future macro metavariable expressions.

A few simplifications and refactors in advance of other work.
Macro metavariable expressions were using
Ident::as_strand doing stringcomparisons; I converted them to use symbols.
I factored out a function for transcribing a
ParseNtResult, which will helpseparate the evaluation and transcription of future macro metavariable
expressions.
