Driver: default to `-fno-use-cxatexit` on Windows This primarily impacts the Windows MSVC and Windows itanium environments. Windows MSVC does not use `__cxa_atexit` and Itanium follows suit. Simplify the logic for the default value calculation and blanket the Windows environments to default to off for use of `__cxa_atexit`. llvm-svn: 312941
