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.
