Currently all generated Regexp functions share the same name making profile information with RegExp functions harder to use. BUG=https://github.com/dart-lang/sdk/issues/51624 TEST=ci Change-Id: I67acf73df4be301dbcb17a60b8be1793002897b4 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/287247 Commit-Queue: Alexander Aprelev <aam@google.com> Reviewed-by: Ryan Macnak <rmacnak@google.com>
