Consider consolidating general checking for TDZ

[yuit]

As @rbuckton point out in PR #4814, we have multiple ways for checking use before definition for many concepts such as this before super, use before declaration for let and const. We should consolidate the checking to be more general purpose that we can extend rather than continuously create new ways of checking

do you have a proposal?

[yuit]

@mhegazy not yet. This is for keeping track for now.

if we do not have a suggestion for an immediate action, i would close this issue. keeping a backlog of engineering work items never worked in the past :)
