Greg Clayton 84db9105d2 <rdar://problem/11113279>
Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not). 

This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method.

This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB.
