    i386: Fix up expansion of 2 keylocker and one user_msr builtin [PR123217]

    target can be especially at -O0 a MEM, not just a REG, and most of the
    ix86_expand_builtin spots which use target and can't support MEM
    destinations deal with it properly, except these 3 spots don't.

    Fixed thusly, when we change target to a new pseudo, the caller will
    take care of storing that pseudo into the MEM, and this is the
    solution other spots with similar requirements use in the function.
