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.
