i386: Use "addr" attribute to limit address regclass to non-REX regs

Use "addr" attribute with "gpr8" value to limit address register class
to non-REX registers in instructions with high registers, where REX
registers can not be used in the address.

gcc/ChangeLog:

	* config/i386/constraints.md (Bc): Remove constraint.
	(Bn): Rewrite to use x86_extended_reg_mentioned_p predicate.
	* config/i386/i386.cc (ix86_memory_address_reg_class):
	Do not limit processing to TARGET_APX_EGPR.  Exit early for
	NULL insn.  Do not check recog_data.insn before calling
	extract_insn_cached.
	(ix86_insn_base_reg_class): Handle ADDR_GPR8.
	(ix86_regno_ok_for_insn_base_p): Ditto.
	(ix86_insn_index_reg_class): Ditto.
	* config/i386/i386.md (*cmpqi_ext<mode>_1_mem_rex64):
	Remove insn pattern and corresponding peephole2 pattern.
	(*cmpi_ext<mode>_1): Remove (m,Q) alternative.
	Change (QBc,Q) alternative to (QBn,Q).  Add "addr" attribute.
	(*cmpqi_ext<mode>_3_mem_rex64): Remove insn pattern
	and corresponding peephole2 pattern.
	(*cmpi_ext<mode>_3): Remove (Q,m) alternative.
	Change (Q,QnBc) alternative to (Q,QnBn).  Add "addr" attribute.
	(*extzvqi_mem_rex64): Remove insn pattern and
	corresponding peephole2 pattern.
	(*extzvqi): Remove (Q,m) alternative.  Change (Q,QnBc)
	alternative to (Q,QnBn).  Add "addr" attribute.
	(*insvqi_1_mem_rex64): Remove insn pattern and
	corresponding peephole2 pattern.
	(*insvqi_1): Remove (Q,m) alternative.  Change (Q,QnBc)
	alternative to (Q,QnBn).  Add "addr" attribute.
	(@insv<mode>_1): Ditto.
	(*addqi_ext<mode>_0): Remove (m,0,Q) alternative.  Change (QBc,0,Q)
	alternative to (QBn,0,Q).  Add "addr" attribute.
	(*subqi_ext<mode>_0): Ditto.
	(*andqi_ext<mode>_0): Ditto.
	(*<any_or:code>qi_ext<mode>_0): Ditto.
	(*addqi_ext<mode>_1): Remove (Q,0,m) alternative.  Change (Q,0,QnBc)
	alternative to (Q,0,QnBn).  Add "addr" attribute.
	(*andqi_ext<mode>_1): Ditto.
	(*andqi_ext<mode>_1_cc): Ditto.
	(*<any_or:code>qi_ext<mode>_1): Ditto.
	(*xorqi_ext<mode>_1_cc): Ditto.
	* config/i386/predicates.md (nonimm_x64constmem_operand):
	Remove predicate.
	(general_x64constmem_operand): Ditto.
	(norex_memory_operand): Ditto.
