        Description

        There are two typos in andL_rReg_imm instructions in x86_64.ad.

        The first one generates confusing output with PrintOptoAssembly:

        009 movzbq RAX, #255 # long & 0xFF

        and the second generates a non-matching instruction (see rRegI):

        instruct andL_rReg_imm65535(rRegI dst, immL_65535 src)
