Alpha: Rearrange thread info flags fixing two regressions
    
    The removal of the TIF_NOTIFY_RESUME flag, commit a583f1b54249b
    "remove unused TIF_NOTIFY_RESUME flag," resulted in incorrect
    setting of the unaligned access control flags by the prctl syscall.
    
    The re-addition of the TIF_NOTIFY_RESUME flag, commit d0420c83f39f
    "KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures [try #6]"
    further caused problems, namely incorrect operands to assembler code
    as evidenced by:
    
    AS      arch/alpha/kernel/entry.o
    arch/alpha/kernel/entry.S: Assembler messages:
    arch/alpha/kernel/entry.S:326: Warning: operand out of range
    (0x0000000000000406 is not between 0x0000000000000000 and
    0x00000000000000ff)
    
    Both regressions fixed by (1) rearranging TIF_NOTIFY_RESUME flag to be
    in lower 8 bits of the thread info flags, and (2) making sure that
    ALPHA_UAC_SHIFT matches the rearrangement of the thread info flags.
