Allow Unicode extended escapes in ES5 and earlier #50918

DanielRosenwasser · 2022-09-23T08:48:42Z

Previously, I suppose because we didn't want to support emit fully, we didn't parse out Unicode extended escape sequences; however, it doesn't make sense for us not to parse them.

This PR allows us to successfully parse Unicode extended escapes in all language versions, and also emits them without any escapes when emitting to any target lower than ES2015. If we don't want to add new parameters to createIdentifier, I can just add the new tracking information separately in the parser, or we can swap this to just being an error.

Part of support for #50883.
Fixes #50935.

…he es2015 transform.
