464a52227c [OCaml] Use $CAMLORIGIN, an rpath-$ORIGIN-like mechanism in OCaml.
As a result, installations of LLVM in non-standard locations
will not require passing custom -ccopt -L flags when building
the binary, nor absolute paths would be embedded in the cma/cmxa
files. Additionally, the executables will not require changes
to LD_LIBRARY_PATH, although CAML_LD_LIBRARY_PATH still
has to be set for ocamlc without -custom.

See http://caml.inria.fr/mantis/view.php?id=6642.
Note that the patch is approved, but not merged yet.
It will be released in 4.03 and likely 4.02.

Summary:
This in turn allows us to use #includes with cgo that rely on CMake
provided include directories which is particularly useful for handling
generated headers that aren't reasonable to put in an "installable"
location.

7c150bae21 [cmake] Start making LLVM_LIBDIR_SUFFIX effective by adding it to
*numerous* places where it was missing in the CMake build. The primary
change here is that the suffix is now actually used for all of the lib
directories in the LLVM project's CMake. The various subprojects still
need similar treatment.

This is the first of a series of commits to try to make LLVM's cmake
effective in a multilib Linux installation. I don't think many people
are seriously using this variable so I'm hoping the fallout will be
minimal. A somewhat unfortunate consequence of the nature of these
commits is that until I land all of them, they will in part make the
brokenness of our multilib support more apparant. At the end, things
should actually work.

827f4eb6a3 [cmake] Unbreak LLVM-Config.cmake / llvm_expand_dependencies.
The algorithm for sorting libraries in topological order, as
previously implemented, had a few issues:
  * It didn't make any sense.
  * It didn't actually sort libraries in topological order.
  * It hung on some inputs, e.g. "LLVMipo".

This commit replaces the old algorithm with a straightforward port
from llvm-config.cpp.

b3963d680c Pass PRIVATE to target_link_libraries if using shared libraries.
A shared library (unlike a .a), has its dependencies recorded in the library and
we can pass PRIVATE to target_link_libraries.

This patch then removes some bogus dependencies when using
BUILD_SHARED_LIBS=ON. For example, we go from

build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o:
CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp
|| include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so
lib/libLLVMCore.so lib/libLLVMBitReader.so
lib/libLLVMTransformUtils.so lib/libLLVMInstCombine.so
lib/libLLVMScalarOpts.so lib/libLLVMipa.so lib/libLLVMAnalysis.so
lib/libLLVMMCParser.so lib/libLLVMMC.so lib/libLLVMObject.so
lib/libLLVMTarget.so lib/libLLVMProfileData.so

to

build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o:
CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp
|| include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so
lib/libLLVMCore.so lib/libLLVMTransformUtils.so
lib/libLLVMScalarOpts.so lib/libLLVMAnalysis.so lib/libLLVMMC.so
lib/libLLVMTarget.so

In fact, build.ninja goes from 5231028 bytes to 4896759 bytes.

With this, old verisons of bfd ld (2.24 is OK, 2.23 warns) will print a bogus
warning when building with BUILD_SHARED_LIBS.

57c911e4ab Suppress MSVC's equivalent of -Wshadow warnings
IMO we need to clean up some of these, but the member variable one
(C4458) has false positives on static methods.  It is currently firing
on Twine, which has a static method like:
  struct Twine {
    uintptr_t LHS, RHS;
    static void staticMethod() {
      // warning C4458: declaration of 'LHS' hides class member
      uintptr_t LHS;
      ...
    }
  };

We should fix up clang's -Wshadow and clean it up, and then we can
re-enable some of these MSVC warnings.

ee3948fdbe Use llvm-symbolizer to symbolize LLVM/Clang crash dumps.
This change modifies fatal signal handler used in LLVM tools.
Now it attempts to find llvm-symbolizer binary and communicates
with it in order to turn instruction addresses into
function/file/line info entries. This should significantly improve
stack traces readability in Debug builds.

This feature only works on selected platforms (including Darwin
and Linux). If the symbolization fails for some reason, signal
handler will fallback to the original behavior.

7e0a0e282a Fix CMake warning CMP0054: don't quote a variable name that is intended to be
expanded; future versions of cmake may not expand the variable in this case.

dadfd4f0a7 Fix misinterpretation of CMake rule found by a CMake warning (related to CMP0054).
lldb sets the variable SHARED_LIBRARY to 1, which breaks this conditional,
because older versions of CMake interpret

  if ("${t}" STREQUAL "SHARED_LIBRARY")

as meaning

  if ("${t}" STREQUAL "1")

in this case. Change the conditional so it does the right thing with both old
and new CMakes.
