Greg Clayton 1075acafeb Added the ability for clients to grab a set of symbol table indexes and then
add them to a fast lookup map. lldb_private::Symtab now export the following
public typedefs:

namespace lldb_private {

	class Symtab {
		typedef std::vector<uint32_t> IndexCollection;
		typedef UniqueCStringMap<uint32_t> NameToIndexMap;
	};
}

Clients can then find symbols by name and or type and end up with a 
Symtab::IndexCollection that is filled with indexes. These indexes can then
be put into a name to index lookup map and control if the mangled and 
demangled names get added to the map:

bool add_demangled = true;
bool add_mangled = true;
Symtab::NameToIndexMap name_to_index;
symtab->AppendSymbolNamesToMap (indexes, add_demangled, add_mangled, name_to_index).

This can be repeated as many times as needed to get a lookup table that
you are happy with, and then this can be sorted:

name_to_index.Sort();

Now name lookups can be done using a subset of the symbols you extracted from
the symbol table. This is currently being used to extract objective C types
from object files when there is no debug info in SymbolFileSymtab.

Cleaned up how the objective C types were being vended to be more efficient
and fixed some errors in the regular expression that was being used.

Sean Callanan 3b107b172d Added ClangExternalASTSourceCommon, a local superclass
for all our external AST sources that lets us associate
arbitrary flags with the types we put into the AST
contexts.  Also added an API on ClangASTContext that
allows access to these flags given only an ASTContext
and a type.

Because we don't have access to RTTI, and because at
some point in the future we might encounter external
AST sources that we didn't make (so they don't subclass
ClangExternalASTSourceCommon) I added a magic number
that we check before doing anything else, so that we
can catch that problem as soon as it appears.
