8231519b85 Simplify visitObjectLiteralExpression 
I ran into it and the comment at the top tripped me, then I proceeded to
simplify the code.  Patched a bit more of the function to make sure that
the indentation doesn't change, and added tests.

f447838f95 Fix handling of aruments in the emitter 
Two problems are fixed:

* `isArgumentsLocalBinding` did only `PropertyAccessExpression`, now
  it's also doing `PropertyAssignment` (doesn't affect other files,
  since it's only used in the emitter).

* `visitShorthandPropertyAssignment` should call `visitIdentifier` on
  the synthesized id.  (For completion it might be better to make it
  visit the the original?)

Fixes #38594.

33c3e9e2c6 Make processTaggedTemplateExpression visit a returned node 
This problem was introduced in 70399e146e2 (from PR #23801), which added
a `visitTaggedTemplateExpression` case for `TaggedTemplateExpression`,
before that, it would fallback to the default of `visitNode`.  So re-add
that happen in `processTaggedTemplateExpression`.

Since it doesn't hurt, I left a `Debug.checkDefined(property.name)`
instead of `!`-ing it.

Fixes #38558.
