Subject: [PATCH 1/2] [clang-tidy] Fix support for typedefs in
readability-identifier-naming
Typedef rename were not properly handled when typedef were used
behind pointer, or as a part of function type. Additionally
because entire function were passed as an source-range, when
function started with macro, such change were not marked for a fix.
Removed workaround and used proper TypedefTypeLoc instead.
