[lldb][NFC] Extract searching for function SymbolContexts out of
ClangExpressionDeclMap::LookupFunction
This code was just creating a new SymbolContextList with any found
functions in the front and orders them by how close they are to the
current frame. This refactors this code into its own function to make
this more obvious.
Doesn't do any other changes to the code, so this is NFC.

Fix compatibility with python3 of clang-include-fixer.py
clang-include-fixer was recently updated to be python3-compatible. 
However, an exception handling clause was improperly using the
deprecated `message` property of Exception classes, so the code was not
yet entirely python3-compatible.

[VPlan] Add dump function to VPlan class.
This adds a dump() function to VPlan, which uses the existing 
operator<<.
This method provides a convenient way to dump a VPlan while debugging, 
e.g. from lldb.
