This un-breaks a lit workflow where you run lit tests from a test
sub-directory within clang without first building clang-func-mapping.

This patch introduces a class that can help to build tools that require cross
translation unit facilities. This class allows function definitions to be loaded
from external AST files based on an index. In order to use this functionality an
index is required. The index format is a flat text file but it might be
replaced with a different solution in the near future. USRs are used as names to
look up the functions definitions. This class also does caching to avoid
redundant loading of AST files.
Right now only function defnitions can be loaded using this API because this is
what the in progress cross translation unit feature of the Static Analyzer
requires. In to future this might be extended to classes, types etc.

There were two issues, one Python 3 specific related to Unicode,
and another which is that the tool substitution for lld no longer
rejected matches where a / preceded the tool name.

debuginfo-tests has need to reuse a lot of common configuration
from clang and lld, and in general it seems like all of the
projects which are tightly coupled (e.g. lld, clang, llvm, lldb,
etc) can benefit from knowing about one other. For example,
lldb needs to know various things about how to run clang in its
test suite. Since there's a lot of common substitutions and
operations that need to be shared among projects, sinking this
up into LLVM makes sense.
In addition, this patch introduces a function add_tool_substitution
which handles all the dirty intricacies of matching tool names
which was previously copied around the various config files. This
is now a simple straightforward interface which is hard to mess
up.

This follows in line with a previous patch of renaming LLVM's.
Working on these files is difficult in certain operating systems
and/or environments that don't like handling python code with a
non .py file extension.
