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
every provided Linux sysroot.

Now that the structure of Fuchsia SDK has been formalized, we no
longer need to pass all the different CFLAGS/LDFLAGS to the CMake
build separately, we can simply set the FUCHSIA_SDK variable and
derive all the necessary variables from that one inside the cache
file.

We want to build the second stage compiler with libc++ and compiler-rt,

This doesn't make any difference since we don't use RPATH/RUNPATH

manually, which gains us the `-stripped` install targets to perform

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
dumper, otherwise Clang relies on the -fcolor-diagnostics flag which we
pass explicitly from our build system anyway. This eliminates one of the
shared libraries dependencies making the toolchain less reliant on the
host environment.

The support for relax relocations is dependent on the linker and
different toolchains within the same compiler can be using different
linkers some of which may or may not support relax relocations.
Give toolchains the option to control whether they want to use relax
relocations in addition to the existing (global) build system option.

Summary:
The clang-proto-fuzzer models a subset of C++ as a protobuf and
uses libprotobuf-mutator to generate interesting mutations of C++
programs. Clang-proto-fuzzer has already found several bugs in
Clang (e.g., https://bugs.llvm.org/show_bug.cgi?id=33747,
https://bugs.llvm.org/show_bug.cgi?id=33749).
As with clang-fuzzer, clang-proto-fuzzer requires the following
cmake flags:
- CMAKE_C_COMPILER=clang
- CMAKE_CXX_COMPILER=clang++
- LLVM_USE_SANITIZE_COVERAGE=YES // needed for libFuzzer
- LLVM_USE_SANITIZER=Address // needed for libFuzzer
In addition, clang-proto-fuzzer requires:
- CLANG_ENABLE_PROTO_FUZZER=ON
clang-proto-fuzzer also requires the following dependencies:
- binutils // needed for libprotobuf-mutator
- liblzma-dev // needed for libprotobuf-mutator
- libz-dev // needed for libprotobuf-mutator
- docbook2x // needed for libprotobuf-mutator
- Recent version of protobuf [3.3.0 is known to work]
A working version of libprotobuf-mutator will automatically be
downloaded and built as an external project.
Implementation of clang-proto-fuzzer provided by Kostya
Serebryany.

By creating this target other projects that depend on clang-generated headers (like LLDB) will no longer be order-dependent on Clang being processed by CMake first.
Also, by creating a dummy of this target in ClangConfig.cmake, projects that can build against out-of-tree clang can freely depend on the target without needing to have conditionals for if clang is in-tree or out-of-tree.
