obviously be improved, but this is the minimal fix and restores us to the
previous behavior.

 - MultiTestRunner will eventually be renamed to 'lit', for LLVM integrated
   tester/testing. This has the pros of being pronouncable and short.

 - "Project" level configuration lives in 'lit.cfg', which is also what lit uses
   to find the root testing directory in some cases. This can be overridden for
   use in project files which want to precisely specify where things are.

 - TestRunner.py is not longer able to be invoked directly.
 
 - Moved some code to Util.py.

 - Introduced a configuration object.

 - Cleaned up --help, removed a few not-very-useful options.

 - Tried not to break anything that works. :)

agree on this test case, but this change gives us a strong definition
of equivalent types.

 - This is "experimental" code, I am feeling my way around and working out the
   best way to do things (and learning tblgen in the process). Comments welcome,
   but keep in mind this stuff will change radically.

 - This is enough to match "subb" and friends, but not much else. The next step is to
   automatically generate the matchers for individual operands.

created by AnalysisConsumer would be released by an instance of AnalysisManager
and then reused by later instances of AnalysisManager. Ownership of the
PathDiagnosticClient now belongs (for now) in AnalysisConsumer.

We also need this layering (for now) because the HTMLDiagnostiClient requires
that the entire translation unit be processed before emitting diagnostics. This
is done in its destructor (which should also be fixed, but that is another
issue).

This fixes PR 4653.

When fp is not eliminated, instructions with T2_i12 modes will be changed to T2_i8 ones. Take that into consideration when determining stack size limit for reserving register scavenging slot.
