This pull request includes several LVal and PatternLike changes:

Add OptionalMemberExpression to LVal because of the stage 1 proposal a?.b = 1
Add MemberExpression to PatternLike because of it is allowed in the destructuring assignment [a.b] = []
The argument of RestElement and the elements of ArrayPattern must be a PatternLike instead of LVal, because [a?.b] = 1 is invalid though a?.b = 1 is allowed
Breaking change: Remove TSParameterProperty from LVal
Add FunctionParameter alias to cover function parameters: Pattern, Identifier and RestElement. The TSParameterProperty is currently excluded from FunctionParameter because it is only valid in class constructors

The new typing reveals a bug in the do-expression-transform. It is fixed in this PR and new tests are added.

packages/babel-types/src/definitions/core.ts


 export const functionCommon = () => ({
-  params: validateArrayOfType("Identifier", "Pattern", "RestElement"),
+  params: validateArrayOfType("FunctionParameter"),


The alias is named FunctionParameter in order to reserve the Parameter-type AST node for the Class Method Parameter Decorator proposal.

For Babel 9, I also want to use Parameter to store function params type annotations (rather than sticking them on identifier nodes).

- add optional member expression to LVal - add member expression to PatternLike

Thanks!

            ? param.get("argument")
-            : param;
+            : param.isTSParameterProperty()
+              ? param.get("parameter")


Nice that this caught a bug.
