Introduce CRT assembly replacements for __rt_sdiv, __rt_udiv, __rt_udiv64, __rt_sdiv64, __rt_srsh (by reusing the RVCT code) as well as memcpy and memset. For MSFT compatibility, some of the code needs to be explicitly forced to ARM, and the /oldit assembly flag needs to be added. Also, while RVCT_ASM_EXPORT macro invocations have been removed, the replacement code is designed to be as close as possible to the one that would have been generated if using the macros.
