[CMake] Support platform building builtins without a full toolchain
Summary:
This patch adds support for building lib/builtins without a fully functioning toolchain. It allows you to bootstrap a cross-compiler, which previously couldn't be done with CMake.
This patch contains the following specific changes:
* Split builtin-specific code out of config-ix.cmake into builtin-config-ix.cmake
* Split some common CMake functionality needed by both builtins and sanitizers into base-config-ix.cmake
* Made lib/builtins/CMakeLists.txt able to be a top-level CMake configuration
I have tested this on Darwin targeting embedded Darwin, and on FreeBSD x86_64 targeting FreeBSD AArch64.
This patch depends on http://reviews.llvm.org/D19692, and is the last part of http://reviews.llvm.org/D16653.

[InstrProf] Implement static profdata registration
Summary:
The motivating use case is eliminating duplicate profile data registered
for the same inline function in two object files. Before this change,
users would observe multiple symbol definition errors with VC link, but
links with LLD would succeed.
Users (Mozilla) have reported that PGO works well with clang-cl and LLD,
but when using LLD without this static registration, we would get into a
"relocation against a discarded section" situation. I'm not sure what
happens in that situation, but I suspect that duplicate, unused profile
information was retained. If so, this change will reduce the size of
such binaries with LLD.
Now, Windows uses static registration and is in line with all the other
platforms.

[CMake] Support platform building builtins without a full toolchain
Summary:
This patch adds support for building lib/builtins without a fully functioning toolchain. It allows you to bootstrap a cross-compiler, which previously couldn't be done with CMake.
This patch contains the following specific changes:
* Split builtin-specific code out of config-ix.cmake into builtin-config-ix.cmake
* Split some common CMake functionality needed by both builtins and sanitizers into base-config-ix.cmake
* Made lib/builtins/CMakeLists.txt able to be a top-level CMake configuration
I have tested this on Darwin targeting embedded Darwin, and on FreeBSD x86_64 targeting FreeBSD AArch64.
This patch depends on http://reviews.llvm.org/D19692, and is the last part of http://reviews.llvm.org/D16653.
