[Merged by Bors] - Rename check_parser and Identifier

[jedel1043]

Extracted from #2411 to reduce its size a bit.

This PR:

• Renames Identifier to IdentifierName, which is the name stated in the spec.
• Renames the utility function check_parser to check_script_parser to prepare for modules.
• Adds some missing #[inline] and rewrites some patterns.
