Back in the mists of time (2008), it seems TableGen couldn't handle the
patterns necessary to match ARM's CMOV node that we convert select operations
to, so we wrote a lot of fairly hairy C++ to do it for us.

TableGen can deal with it now: there were a few minor differences to CodeGen
(see tests), but nothing obviously worse that I could see, so we should
probably address anything that *does* come up in a localised manner.

Since it's an llvm-internal tool, we shouldn't install it.

 - This cleans up the text output of failing tests when run under PY3.

 - For whatever reason, we have a lot of test files with bogus unicode
   characters. This patch allows those scripts to still be parsed on Python3 by
   changing the parsing logic to work on binary files, and only require the
   actual script commands to be convertible to ascii.

 - This patch has been tweaked to now ensure that the command strings are not of
   unicode type on Python 2.6-7.

Revert r188376, "[lit] Support parsing scripts with inconsistent or invalid encodings.", this doesn't work yet for bots using the internal shell.

 - We barely used it, and it is very hard to use in a 2.5-3 compatible
   way because of changing expectations for its input types.

FileCheck should check to make sure the prefix was found, and not a word
containing it (e.g -check-prefix=BASEREL shouldn't match NOBASEREL).

Apparently caused a failure on Darwin

llvm-svn: 188166

clang bootstraps intermittently failed for me due a difference in
the MCK_Reg ordering in ARMGenAsmMatcher.inc.  E.g. in my latest
run the stage 1 and stage 3 versions were the same but the stage 2
one was different (though still functionally correct).  This meant
that the .o comparison failed.

MCK_Regs were assigned by iterating over a std::set< std::set<Record*> >,
and since std::set is sorted lexicographically, the order depended on the
order of the pointer values.  This patch replaces the pointer ordering
with LessRecordByID.

 - The actual tests have better coverage than those, and they weren't useful
   anymore.

 - With compatibility hack in lit.__init__, so this hopefully shouldn't break
   anything.

 - Injecting it as 'lit' is gross, since that name should be used to refer to
   the actual package. For now both are available so it is possibly to cleanup
   test config files incrementally.
