    Prevent undefined FMOV instructions being accepted by the AArch64
assembler.

        Detect illegal FMOV instructions that changes the size from 32 bits to
64
        bits and vice versa. Add tests for these and other undefined FMOV
        instructions.

            PR 20319
    gas     * testsuite/gas/aarch64/illegal-3.s: Test if unallocated FMOV
encodings
            are detected as undefined.
            * testsuite/gas/aarch64/illegal-3.d: Likewise.
            * testsuite/gas/aarch64/illegal.s: Test if FMOV instructions that
are
            changing the size from 32 bits to 64 bits and vice versa trigger an
            error.
            * testsuite/gas/aarch64/illegal.l: Likewise.

    opcodes * aarch64-tbl.h: Introduce QL_INT2FP_FMOV and QL_FP2INT_FMOV.
            (aarch64_opcode_table) : Use QL_INT2FP_FMOV and QL_FP2INT_FMOV.
