Chandler Carruth ce55f56fbc [cmake] Revert r260742 (and r260744) to improve order file support.
This appears to be passing '-Wl,-order_file' to Linux link commands,
which then causes the linker to silently, behind the scenes, write the
output to 'rder_file' instead of somewhere else. Will work with Chris to
figure out the proper support for this, but so far there are numerous
people who can't get Clang to update when they build because of this.

Chris Bieneman 3878bc4a33 [CMake] Improve the clang order-file generation workflow
Summary:
This commit re-lands r259862. The underlying cause of the build breakage was an incorrectly written capabilities test. In tools/Driver/CMakeLists.txt I was attempting to check if a linker flag worked, the test was passing it to the compiler, not the linker. CMake doesn't have a linker test, so we have a hand-rolled one.

Original Patch Review: http://reviews.llvm.org/D16896

Original Summary:
With this change generating clang order files using dtrace uses the following workflow:

cmake <whatever options you want>

ninja generate-order-file

ninja clang

This patch works by setting a default path to the order file (which can be overridden by the user). If the order file doesn't exist during configuration CMake will create an empty one.

CMake then ties up the dependencies between the clang link job and the order file, and generate-order-file overwrites CLANG_ORDER_FILE with the new order file.

Chris Bieneman fe4a7b3ccd [CMake] Don't apply Export set to clang tools
I can't apply export to tools without getting some strange CMake spew. The behavior here is a bit unexpected. CMake is complaining about static link dependencies not being in the same export set, which shouldn't matter.

In the short term it is easier to just remove the export set (which was just added in r258209) while I sort this out.

This change brings forward the LLVM convention that "executables" are just runnable binaries, and "tools" are executables that are part of the project's install.

Having this abstraction will allow us to simplify some of the tool CMakeLists files, and it will standardize some of the install behaviors.

Chris Bieneman b2920a779c [CMake] Support a simple case for bootstrap builds to generate PGO data
Summary:
This patch adds support for the clang multi-stage bootstrapping to support PGO profdata generation, and can build a 2 or 3 stage compiler.

With this patch applied you can configure your build directory with the following invocation of CMake:

cmake -G <generator> -C <path_to_clang>/cmake/caches/PGO.cmake <source dir>

After configuration the following additional targets will be generated:

stage2-instrumented:
Builds a stage1 x86 compiler, runtime, and required tools (llvm-config, llvm-profdata) then uses that compiler to build an instrumented stage2 compiler.

stage2-instrumented-generate-profdata:
Depends on "stage2-instrumented" and will use the instrumented compiler to generate profdata based on the training files in <clang>/utils/perf-training

stage2:
Depends on "stage2-instrumented-generate-profdata" and will use the stage1 compiler with the stage2 profdata to build a PGO-optimized compiler.

stage2-check-llvm:
Depends on stage2 and runs check-llvm using the stage3 compiler.

stage2-check-clang:
Depends on stage2 and runs check-clang using the stage3 compiler.

stage2-check-all:
Depends on stage2 and runs check-all using the stage3 compiler.

stage2-test-suite:
Depends on stage2 and runs the test-suite using the stage3 compiler (requires in-tree test-suite).

Chris Bieneman c146ea45f5 [CMake] Name the bootstrap stages stage[0-9]
When you start chaining bootstrap stages the CMake-generated targets get unwieldy. This change supports naming the bootstrap targets and creating wrapper targets in the top-level build file.

Without this patch the default target generated for a second stage build was "bootstrap" with it the target is "stage2".

Also with some CMake goop setting CLANG_BOOTSTRAP_TARGETS, you can expose third stage targets as "stage3" instead of "bootstrap-bootstrap"

Chris Bieneman ae5433907a [CMake] Add support for generating profdata for clang from training files
Summary:
This patch adds support for using LIT to drive generating PGO profile data for clang.

This first pass implementation should work on Linux and Unix based platforms. If you build clang using CMake with LLVM_BUILD_INSTRUMENTED=On the CMake build generates a generate-profdata target that will use the just-built clang to build any test files (see hello_world.cpp as an example). Each test compile will generate profraw files for each clang process. After all tests have run CMake will merge the profraw files using llvm-profdata.

Future opportunities for extension:
* Support for Build->Profile->Build bootstrapping
* Support for linker order file generation using a similar mechanism and the same training data
* Support for Windows

(3) BOOTSTRAP_DEFAULT_PASSTHROUGH is a list of some default passthrough variables that are always passed through. Those variables include the version string and should only specify variables that are always expected to be the same between the stage1 and stage2
