This patch starts to vendor functionalities from STL using our own code.
It adds a
SNMALLOC_USE_SELF_VENDORED_STLoption which meanssnmallocwill try to build its core header library withoutc++STL.The way we do this is to introduce a
proxywhich dispatches underlying implementations based onSNMALLOC_USE_SELF_VENDORED_STL. It is allowed to use STL in tests even whenSNMALLOC_USE_SELF_VENDORED_STL=On.This patch only includes changes related to
std::atomic. Thesnmalloc::Atomicis simple wrapper of compiler intrinsics that only support trivial types with unique object representations.
