    Use double quotes in some gdb output
    
    I looked for spots where gdb was using `...' or ``...'' quoting, and
    changed these to use double quotes instead.
    
    I think it might be good to regularize output quoting in gdb.  My
    proposal is to use double quotes, though single quotes would also be
    fine.  Using `...', though, is a kind of older style and has fallen
    out of favor in GNU; the relevant node is here:
    
        https://www.gnu.org/prep/standards/html_node/Quote-Characters.html
