Julian Lettner	e1b82d852d	Remove dlsym() lookup for TSan functions from common path (#36478) ... * Move TSan function lookup out of the common path Move TSan function lookup via `dlsym()` out of the common path. The TSan runtime will now call `__tsan_on_initialize()` which we can use to initialize the TSan functions in the Swift runtime. This avoids paying the cost of `dlsym()` in the common, non-TSan case. Depends on: https://reviews.llvm.org/D98810 rdar://75493372 * Remove Windows code Thread Sanitizer is not supported on Windows.
