[JSC] Inline common fast path for op_resolve_scope and op_get_from_scope
https://bugs.webkit.org/show_bug.cgi?id=276631
rdar://131788827
Reviewed by Yijia Huang.
GlobalProperty, GlobalVar, and GlobalLexicalVar are common, and most of code
for them are pretty small.
While these resolution can be changed for each CodeBlock, we cannot use the one
specific type like ClosureVar,
we can inline the most possible one as a fast path.
