… aid inlining (#7322) Move the cheap "does arguments need to be transformed" checks introduced in #7321 into `enter_identifier_reference` and `enter_binding_identifier`, and mark those methods `#[inline]`. These hot paths can then usually execute without a function call. This wins back the other half of the perf hit of #7234.

Track whether
argumentsneeds to be transformed. If it doesn't, can skip expensive checks for whetherIdentifierReferences andBindingIdentifiers names areargumentsor not.This recovers about half the performance hit of #7234.
