i386: Emulate MMX ssse3_palignrdi with SSE

Emulate MMX version of palignrq with SSE version by concatenating 2
64-bit MMX operands into a single 128-bit SSE operand, followed by
SSE psrldq.  Only SSE register source operand is allowed.

PR target/89021
* config/i386/sse.md (ssse3_palignrdi): Changed to
define_insn_and_split to support SSE emulation.
