When cross-compiling the second stage to a different target, we need to
make sure that the first-stage compiler can produce binaries for that
target. Using lld and llvm-objcopy as the default linker and objcopy
tool eliminates some of the dependencies on the host toolchain.

When second stage is being cross-compiled for a different platform
we need to build enough of first stage runtimes to get a working

Summary:
Enhanced support for Z3 in the cmake configuration of clang; now it is possible to specify any arbitrary Z3 install prefix (CLANG_ANALYZER_Z3_PREFIX) to cmake with lib (or bin) and include folders. Before the patch only in cmake default locations
were searched (https://cmake.org/cmake/help/v3.4/command/find_path.html).
Specifying any CLANG_ANALYZER_Z3_PREFIX will force also CLANG_ANALYZER_BUILD_Z3 to ON.
Removed also Z3 4.5 version requirement since it was not checked, and now Clang works with Z3 4.7

clang tools require clang headers to work on real project, e.g. when we

When building libc++ for Fuchsia, we want to distribute shared libc++,

Previously we were using default logic when building Linux runtimes
in Fuchsia toolchain, but that leads to various issues due to how
the CMake logic in compiler-rt for determining the platform support
is implemented. With this change, we will use explicit target for

Now that the structure of Fuchsia SDK has been formalized, we no

file.

It's used to determine whether terminal supports colors, but within LLVM
it's only used in handful of places and in Clang it's only used in AST

shared libraries dependencies making the toolchain less reliant on the
