re PR rtl-optimization/57032 (internal compiler error: Max. number of generated reload insns per insn is achieved (90))
PR target/57032
* config/alpha/constraints.md (Q): Rewrite as define_memory_constraint.
Check for a memory location that is not a reference (using an AND)
to an unaligned location here.
* config/alpha/predicates.md (normal_memory_operand): Remove.
