This patch implements out of line atomics for LSE deployment mechanism. Details how it works can be found in llvm/docs/Atomics.rst Options -moutline-atomics and -mno-outline-atomics to enable and disable it were added to clang driver. This is clang and llvm part of out-of-line atomics interface, library part is already supported by libgcc. Compiler-rt support is provided in separate patch.
