描述

Windows does not provide a stable ABI between debug and release mode. This requires that we provide a debug build of swiftrt.obj and adjust the driver to select the proper version of swiftrt.obj when linking. This should allow us to build in Debug configurations without running into _ITERATOR_DEBUG_LEVEL mismatches.

研究方向
Investigate the current build of swiftrt.obj for Windows in the Swift repository. Look at the CMake files to understand how the runtime object is built and how the driver selects the version. Check for any existing debug configuration settings. The goal is to create a debug variant (swiftrtd.o) and modify the driver to link the appropriate version based on build configuration.
