From INSTRUCTION EXCEPTION SPECIFICATION section in Intel software
developer manual volume 2, only legacy SSE instructions with memory
operand not 16-byte aligned get General Protection fault. There is
no need to check 1, 2, 4, 8 byte alignments. Since x86 backend has
accurate constraints and predicates for 16-byte alignment, we can
remove alignment check in ix86_legitimate_combined_insn.
* config/i386/i386.c (ix86_legitimate_combined_insn): Remove
alignment check.
* config/i386/i386.md (ssememalign): Removed.
* config/i386/sse.md: Remove ssememalign attribute from patterns.
