RISC-V: Support Zcmp push/pop instructions.
Support zcmp extension push/pop/popret and popret zero instructions.
The `reg_list' is a list containing 1 to 13 registers, we can use:
"{ra}, {ra, s0}, {ra, s0-s1}, {ra, s0-s2} ... {ra, s0-sN}"
to present this feature.
Passed gcc/binutils regressions of riscv-gnu-toolchain.
Most of work was finished by Sinan Lin.

bfd/ChangeLog:
* elfxx-riscv.c (riscv_implicit_subset): Imply zca for zcmp.
(riscv_supported_std_z_ext): Added zcmp with version 1.0.
(riscv_parse_check_conflicts): Zcmp conflicts with d/zcd.
(riscv_multi_subset_supports): Handle zcmp.
(riscv_multi_subset_supports_ext): Ditto.
gas/ChangeLog:
* NEWS: Updated.
* config/tc-riscv.c (regno_to_reg_list): New function, used to map
register to reg_list number.
(reglist_lookup): Called reglist_lookup_internal. Return false if
reg_list number is zero, which is an invalid value.
(reglist_lookup_internal): Parse register list, and return the last
register by regno_to_reg_list.
(validate_riscv_insn): New operators.
(riscv_ip): Ditto.
* testsuite/gas/riscv/march-help.l: Updated.
* testsuite/gas/riscv/zcmp-push-pop-fail.d: New test.
* testsuite/gas/riscv/zcmp-push-pop-fail.l: New test.
* testsuite/gas/riscv/zcmp-push-pop-fail.s: New test.
* testsuite/gas/riscv/zcmp-push-pop.d: New test.
* testsuite/gas/riscv/zcmp-push-pop.s: New test.
include/ChangeLog:
* opcode/riscv-opc.h (MATCH/MASK_CM_PUSH): New macros for zcmp.
(MATCH/MASK_CM_POP): Ditto.
(MATCH/MASK_CM_POPRET): Ditto.
(MATCH/MASK_CM_POPRETZ): Ditto.
(DECLARE_INSN): New declarations for zcmp.
* opcode/riscv.h (EXTRACT/ENCODE/VALID_ZCMP_SPIMM): Handle spimm
operand for zcmp.
(OP_MASK_REG_LIST): Handle operand for zcmp register list.
(OP_SH_REG_LIST): Ditto.
(ZCMP_SP_ALIGNMENT): New argument, used in riscv_get_sp_base.
(X_S0, X_S1, X_S2, X_S10, X_S11): New register numbers.
(enum riscv_insn_class): Added INSN_CLASS_ZCMP.
(extern riscv_get_sp_base): Added.
opcodes/ChangeLog:
* riscv-dis.c (print_reg_list): New function, used to get zcmp
reg_list field.
(riscv_get_spimm): New function, used to get zcmp sp adjustment
immediate.
(print_insn_args): Handle new operands for zcmp.
* riscv-opc.c (riscv_get_sp_base): New function, used by gas and
objdump. Get sp base adjustment.
(riscv_opcodes): Added zcmp instructions.
