  [clang][CodeComplete] Dont perform fallback completion for incomplete member ref

Summary:
Clang performs expression based completion whenever it can't figure out
base of a member reference expression. It might be quite confusing in cases like
incomplete types. This patch disables that fallback.

Unfortunately `ParsePostfixExpressionSuffix` is quite tangled and this patch
adds more to it.
