    Remove non-address bits for longjmp resume breakpoint
    
    On 32-bit S390 targets the longjmp target address "naturally" has the
    most significant bit set.  That bit indicates the addressing mode and
    is not part of the address itself.  Thus, in analogy with similar
    cases (like when computing the caller PC in
    insert_step_resume_breakpoint_at_caller), this change removes
    non-address bits from the longjmp target address before using it as a
    breakpoint address.
    
    Note that there are two ways for determining the longjmp target
    address: via a probe or via a gdbarch method.  This change only
    affects the probe method, because it is assumed that the address
    returned by the gdbarch method is usable as-is.
    
    This change was tested together with a patch that enables longjmp
    probes in glibc for S/390:

    	gdbarch_addr_bits_remove to longjmp resume address.
