Message:

iprt/asm.h: Cleaned up the ASMMemIsAll8/U32 mess and implmeneted the former in assembly. (Found inverted usage due to bad naming in copyUtf8Block, but it is fortunately an unused method.) Replaces the complicated ASMBitFirstSet based scanning in RTSgBufIsZero with a simple call to the new ASMMemIsZero function.
