[PATCH 21/43] i386: Emulate MMX maskmovq with SSE2 maskmovdqu

Emulate MMX maskmovq with SSE2 maskmovdqu in 64-bit mode by zero-extending source and mask operands to 128 bits. Handle unmapped bits 64:127 at memory address by adjusting source and mask operands together with memory address. PR target/89021 * config/i386/xmmintrin.h: Emulate MMX
