[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. Reviewers: samsonov, iains, jroelofs Subscribers: compnerd, aemerson, tberghammer, danalbert, srhines, emaste, llvm-commits Differential Revision: http://reviews.llvm.org/D19742 llvm-svn: 268977
