[PATCH] D46625: [asan] Enable memtrinsics interception for RTEMS

[Walter Lee via Phabricator via llvm-commits]

Herald added a subscriber: kubamracek.

Replace decltype(memcpy) with decltype(__asan_memcpy) because memcpy
has not been defined in any headers on RTEMS.  Similarly for memmove
and memset.
