[commit] use get_frame_memory where easy

[Richard Henderson <rth@twiddle.net>]

AFAICT, the rest of the places get called from hooks that don't
have access to the frame.

        * alpha-tdep.c (alpha_next_pc): Use alpha_read_insn.
        (alpha_sigtramp_frame_this_id): Use get_frame_memory.
        (alpha_sigtramp_frame_prev_register): Likewise.
        (alpha_heuristic_frame_prev_register): Likewise.
        * alpha-mdebug-tdep.c (alpha_mdebug_frame_prev_register): Likewise.
