* config/i386/i386.c (memory_address_length): Handle %r12
the same as %rsp and %r13 the same as %rbp. For %rsp and %rbp
also check REGNO.
(ix86_attr_length_address_default): For MODE_SI lea in 64-bit
mode look through optional ZERO_EXTEND and SUBREG.
* config/i386/i386.md (R12_REG): New define_constant.
(prefix_data16): For sse unit set also for MODE_TI insns.
(prefix_rex): For -m32 always return 0. For TYPE_IMOVX
insns set if operand 1 is ext_QIreg_operand.
(modrm): For TYPE_IMOV clear only if not MODE_DI. For
TYPE_{ALU{,1},ICMP,TEST} insn clear if there is non-shortened
immediate.
(*movdi_extzv_1, zero_extendhidi2, zero_extendqidi2): Change
mode from MODE_DI to MODE_SI.
(movdi_1_rex64): Override modrm and length_immediate attributes
only for movabs (TYPE_IMOV, alternative 2).
(zero_extendsidi2_rex64): Clear prefix_0f attribute if TYPE_IMOVX.
(*float<SSEMODEI24:mode><MODEF:mode>2_mixed_interunit,

attribute to 1 if TYPE_ALU and operand 2 is const128_operand.
(pro_epilogue_adjust_stack_1, pro_epilogue_adjust_stack_rex64):
Likewise. For TYPE_IMOV clear length_immediate attribute.
