Use movaps / movd to extract vector element 0 even with sse4.1. It's still cheaper than pextrw especially if the value is in memory.

reason. Two functions which mutually require each other to be nocapture 
are not currently supported.

functions that don't write can't leak a pointer except through 
the return value, so a void readonly function is implicitly nocapture.

Test these, and add a test that verifies that f1 calling f2 with an 
otherwise dead pointer gets both of them marked nocapture.

promote from i1 all the way up to the canonical SetCC type.
In order to discover an appropriate type to use, pass
MVT::Other to getSetCCResultType.  In order to be able to
do this, change getSetCCResultType to take a type as an
argument, not a value (this is also more logical).

* Added the first LLVM unittest -- DenseMap.
* Updated mkpatch utility to include llvm/unittests dir
* Added top-level target "unittests" to run all unittests

* Removed gtest_main.cc: we have our own main() elsewhere
* Simplified the Makefile as we don't need SOURCES

* Moved the internal header to gtest/internal/
* Simplified the Makefile to remove -I param to CPP.Flags

* Updated README.LLVM with all the steps I took to massage GTest to
  work in LLVM so far

Also added Makefiles at every level of the directory tree to properly recurse
to Google Test and build it as a library (original Makefiles by Talin).
