docs/TestingGuide: Minimal update to describe 'lit' based regression testing
instead of DejaGNU. Still a bit kooky, since the current test format still has
some strong Tcl roots. Oh well!

docs/TestingGuide: Rip out description of old nightly tester infrastructure. The
official recommendation is to use LNT instead. I will write docs on setting up
an LNT installation for submission to llvm.org, one day.

tests: Deprecate TestRunner.sh, and have it just invoke 'llvm-lit' (which will
need to be in your path). Please move to using 'llvm-lit' if you are still using
TestRunner.sh.

tests: Add an 'llvm-lit' tool (script), which gets generated as part of the
build and has the object build directory baked into it. This allows 'llvm-lit'
to properly find the information needed to run the test suite in all cases,
without requiring the user to have LLVM or 'lit' available in their PATH, for
example.

tests: Make 'lit' the default test tool. You can still use 'make check-dg' to
run the tests using DejaGNU, but not for much longer. This is a last call for
DejaGNU supporters, if no one complains soon the DejaGNU support is going to
die.
