C++: add support for local types

Browse Source 
This change addes support for class, enum definition inside blocks({}) or
functions, e.g.:
void f()
{
	struct S
	{
		int bar;
	};
	S s;
	s.bar;
}

It fixes:
* code completion
* highlighting
* follow symbol
* marking
* find usages

It fixes also problem with namespace aliases inside blocks or functions.

This change can have also impact on performance(there are additional processing)
