This patch allows us to use cmake to specify a cross compiler for Hexagon.
In particular, the patch adds a missing case for the target Hexagon in
cmake/config-ix.cmake, and it moves LLVM_DEFAULT_TARGET_TRIPLE and TARGET_TRIPLE
variables from cmake/config-ix.cmake to the toplevel CMakeLists.txt to make them
available at configure time. Here is the command line that I have used to test
my patches:
$ cmake -G Ninja -D BUILD_SHARED_LIBS:BOOL=ON -D LLVM_TARGETS_TO_BUILD:STRING=Hexagon -D TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_DEFAULT_TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_TARGET_ARCH:STRING=hexagon-unknown-linux-gnu -D LLVM_ENABLE_PIC:BOOL=OFF ..
$ ninja check

yaml2obj takes a textual description of an object file in YAML format
and outputs the binary equivalent. This greatly simplifies writing
tests that take binary object files as input.

re-used. Also, build in direct support for accumulating a set of lit
parameters, arguments, and testsuites to run as part of a 'check-all'
rule. This sinks 'check-all' from a Clang-specific construct to
a generic construct of the project.

optional library support to the llvm-build tool:
- Add new command line parameter to llvm-build: “--enable-optional-libraries”
- Add handing of new llvm-build library type “OptionalLibrary”
- Update Cmake and automake build systems to pass correct flags to llvm-build
based on configuration

The new target machines are:
nvptx (old ptx32) => 32-bit PTX
nvptx64 (old ptx64) => 64-bit PTX
The sources are based on the internal NVIDIA NVPTX back-end, and
contain more functionality than the current PTX back-end currently
provides.

Also refactor the existing OProfile profiling code to reuse the same interfaces with the VTune profiling code.
In addition, unit tests for the profiling interfaces were added.

This is useful for clients that want to maintain compatibility
across multiple releases of LLVM. Currently users like Klee and
Mesa all have to roll their own 'parse llvm-config --version
output and generate defines' solution.
Also reuse the new macros so that version information is less
redundant/likely to fall out of sync again in the future.

It could only be specified on the commandline, and wouldn't show
up as an option in the GUI or when invoked via `cmake -i` at all.
This also tells CMake that it's a BOOL, rather than "UNINITIALIZED".

And fix the double-[]. It was including the [] as part of
the project name somehow, resulting in PACKAGE_TARNAME "-llvm-"
and a strange docdir default:
./configure --help | grep docdir
--docdir=DIR documentation root [DATAROOTDIR/doc/-llvm-]

of the targets we know about. Because this is cached, rebuilds won't
detect when new targets show up. It's also a bit simpler to just say
"all". If users want to restrict the target set, they can still do so,
and then the cache will preserve what they have explicitly set this
field to.

Original commit message:
llvm-config: Replace with C++ version (was llvm-config-2).
- Reapply of r144300, with lots of fixes/migration easement in between.

- Generates the llvm-config-2 LibraryDependencies.inc file.
- Generates dependency information so that cmake will automatically reconfigure
when LLVMBuild.txt files are changed.

Stefanovic. I removed the part that actually emits the instructions cause
I want that to get in better shape first and in incremental steps. This
also makes it easier to review the upcoming parts.

When building LLVM/Clang on Solaris. The generated makefiles would
have an extraneous semi-colon character in them prior to this change
due to the way the 'CMAKE_CXX_FLAGS' variable was defined. Simply
adjusting the definition by moving the current CMAKE_CXX_FLAGS value
within the quotes solves the problem.

under cmake).
Add libprofile_rt.a so that we can tell clang to link against it in --coverage
mode. Also turn it on by default in cmake builds.
Oscar, this touches a change you made for EXCLUDE_FROM_ALL support -- I think
I've done the right thing, but please let me know (or fix and commit) if not!
