747b2ba2b9 Work in progress. 
Start cleaning up MergeFunctions to look more like the rest of LLVM. The
primary change here is to move the methods responsible for comparison into the
new FunctionComparator object. Some comments added. There's more to do.

87c74ac6e5 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!

e6c5d8507a tests: Deprecate TestRunner.sh, and have it just invoke 'llvm-lit' (which will

53385ca642 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.

138136572f 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.

75734bc143 The BlockExtractorPass() constructor was not reading the BlockFile and that was 
exactly what bugpoint expected it to do.

There was also only one user of
BlockExtractorPass(const std::vector<BasicBlock*> &B), so just remove it and
make BlockExtractorPass read BlockFile.

This fixes bugpoint's block extraction.

Nick, please review.

f70b028327 Add a "Compare" flag to the target instruction descriptor. This will be used 
later to identify and possibly remove superfluous compare instructions -- those
that are testing for and setting a status flag that should already be set.

eb251be031 PPC doesn't supported VLA with large alignment. This was 
formerly rejected by the FE, so asserted in the BE; now the FE only
warns, so we treat it as a legitimate fatal error in PPC BE.
This means the test for the feature won't pass, so it's xfail'd.

0c0dd2173c Support all 128-bit AVX vector intrinsics. Most part of them I already 
declared during the addition of the assembler support, the additional
changes are:
- Add missing intrinsics
- Move all SSE conversion instructions in X86InstInfo64.td to the SSE.td file.
- Duplicate some patterns to AVX mode.
- Step into PCMPEST/PCMPIST custom inserter and add AVX versions.
