* Destructuring declaration prefers type annotation type

Previously, getTypeForBindingElement would always union the declarations type and
the type of the default initializer. Now, if the declaration has a type
annotation, it does not union with the initializer type. The type
annotation's type is the one used.

* Small cleanup in parentDeclarationHasTypeAnnotation

* Refactoring based on PR comments

* Combine getCombined*Flags into a single helper function

Retain the individual functions since they are used a lot.

* Remove unneeded temp
