RISC-V: Fix RV32Q conflict
This commit makes RV32 + 'Q' extension (version 2.2 or later) not
conflicting since this combination is no longer prohibited by the
specification.
bfd/ChangeLog:
* elfxx-riscv.c (riscv_parse_check_conflicts): Remove conflict
detection that prohibits RV32Q on 'Q' version 2.2 or later.
gas/ChangeLog:
* testsuite/gas/riscv/march-fail-rv32iq.d: Removed.
* testsuite/gas/riscv/march-fail-rv32iq.l: Likewise.
* testsuite/gas/riscv/march-fail-rv32iq2p0.d: New test
showing RV32IQ fails on 'Q' extension version 2.0.
* testsuite/gas/riscv/march-fail-rv32iq2p0.l: Likewise.
* testsuite/gas/riscv/march-fail-rv32iq2.d: Likewise.
* testsuite/gas/riscv/march-fail-rv32iq-isa-2p2.d: New test
showing RV32IQ fails on ISA specification version 2.2.
* testsuite/gas/riscv/march-ok-rv32iq2p2.d: New test
showing RV32IQ succesds on 'Q' extension version 2.2.
* testsuite/gas/riscv/march-ok-rv32iq-isa-20190608.d: New test
showing RV32IQ succesds on ISA specification 20190608.
