clang-p2996/lldb/test/functionalities/data-formatter/data-formatter-cpp/TestDataFormatterCpp.py
Enrico Granata 02b6676d2b Third round of code cleanups:
- reorganizing the PTS (Partial Template Specializations) in FormatManager.h
 - applied a patch by Filipe Cabecinhas to make LLDB compile with GCC
Functional changes:
 - fixed an issue where command type summary add for type "struct Foo" would not match any types.
   currently, "struct" will be stripped off and type "Foo" will be matched.
   similar behavior occurs for class, enum and union specifiers.
