Supply c++11 flags and per-project info to c++ code model.

A manual squash/merge of the changes below, plus a couple of subsequent
code fixes.

59085aa5fbb99e2d786cd2c1a06c24a111ccb49f:
    Modify CppModel::ProjectInfo

    Adding per project node information, to pass on the correct
    defines/includes for each file, instead of aggregating them incorrectly.

    Also split up SOURCES and OBJECTIVE_SOURCES.

    Also ask the toolchain to convert the compilerflags to flags the
    codemodel understands, for now only gcc and only c++11.

    Also make the toolchain aware of the flags used to compile, so that it
    can emit the correct defines.

    Note: No header files are passed on.

74028802314cd4e75b41b46407433e07090a304d:
    GCC: Evaluate cxxflags when checking for predefined macros

ebaaa4957e4c02cc9637a998eddae1d0acd74f83:
    MSVC: Take cxxflags into account when checking for predefined macros

    Compile fixes
