Remaining problems for class properties transform

[overlookmotel]

Remaining issues:

Correctness

In order of how likely they are to affect real world code:

• Co-ordinate class properties transform with TS transform (possibly solved by fix(transformer/class-properties): run other transforms on static properties, static blocks, and computed keys #7982, but need to make sure).
• Run other transforms on inserted statements. (fix(transformer/class-properties): run other transforms on static properties, static blocks, and computed keys #7982)
• Variable collisions between instance prop initializers and constructor. (fix(transformer/class-properties): fix symbol clashes in instance prop initializers #7872)
• Transform super in static prop initializers. (Partially completed in feat(transformer/class-properties): transform super member expressions that are inside static prop initializer #7815 and feat(transformer/class-properties): transform super call expression that is inside static prop initializer #7831)
• Replace class name and this with temp var in static blocks. (fix(transformer/class-properties): replace this and class name in static blocks #8035)
• Transform super in static blocks. (fix(transformer/class-properties): replace this and class name in static blocks #8035)
• Shadowed class name in transpiled static private field (e.g. private/static-shadow/input.js fixture).
• Run other transforms on _super function outside class.
• Transform class name and super in _super function outside class.
• Infer name of class expressions.
• TDZ violations in computed keys - referring to class name within computed key.

The last 4 are very unlikely to have real-world impact.

Improvements / optimizations / required to pass tests

• Private fields with loose option / privateFieldsAsProperties assumption (partially completed in feat(transformer/class-properties): support private_fields_as_properties assumption #7717).
• Correct scopes in instance prop initializers. (fix(transformer/class-properties): fix ScopeIds in instance prop initializers #7823)
• Correct scopes in static prop initializers. (fix(transformer/class-properties): fix ScopeIds in static prop initializers #7791)
• Correct scope flags in static prop initializers. (fix(transformer/class-properties): fix scope flags in static prop initializers #7786)
• Improve computed prop key side effect detection.

• Handful of other small issues noted in TODO comments in implementation code.
