* 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

Makefile with it, without resorting to the use of VPATH.
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).

Added a README.LLVM file to indicate which files and directories
were removed from the original source tarball.

to work out (in a very simplistic way) which function
arguments (pointer arguments only) are only dereferenced
and so do not escape. Mark such arguments 'nocapture'.

instruction sequence and cannot ordinarily be simplified by DAGcombine
into the various target description files or SPUDAGToDAGISel.cpp.
This makes some 64-bit operations legal.
- Eliminate target-dependent ISD enums.
- Update tests.

and select instructions doesn't buy anything here
except extra complexity: the only difference in
the entire testsuite was that a readonly function
became readnone in MiBench/consumer-typeset. Add
a comment about this.

constants, since doing so is irrelevant for aliasing
purposes. While this doesn't increase the total number
of functions marked readonly or readnone in MultiSource/
Applications (3089), it does result in 12 functions being
marked readnone rather than readonly.
Before:
readnone: 820
readonly: 2269
After:
readnone: 832
readonly: 2257

- Move v4i32, i32 mul into SPUInstrInfo.td, with a few more instruction
cleanups there as well.
- Make SMUL_LOHI, UMUL_LOHI competely illegal for Cell SPU, to better
assist Chris to see the problem in bug 3101.

DAGcombine's ability to find reasons to remove truncates when they were not
needed. Consequently, the CellSPU backend would produce correct, but _really
slow and horrible_, code.
Replaced with instruction sequences that do the equivalent truncation in
SPUInstrInfo.td.
- Re-examine how unaligned loads and stores work. Generated unaligned
load code has been tested on the CellSPU hardware; see the i32operations.c
and i64operations.c in CodeGen/CellSPU/useful-harnesses. (While they may be
toy test code, it does prove that some real world code does compile
correctly.)
- Fix truncating stores in bug 3193 (note: unpack_df.ll will still make llc
fault because i64 ult is not yet implemented.)
- Added i64 eq and neq for setcc and select/setcc; started new instruction
information file for them in SPU64InstrInfo.td. Additional i64 operations
should be added to this file and not to SPUInstrInfo.td.
