* tramp-frame.h (struct tramp_frame): Change "insn" to a struct
containing both bytes and mask. Add "frame_type".
* tramp-frame.c (tramp_frame_start): Update.
(tramp_frame_prepend_unwinder): Update.
* mips-linux-tdep.c (mips_linux_o32_sigframe)
(mips_linux_o32_rt_sigframe, mips_linux_n32_rt_sigframe)
(mips_linux_n64_rt_sigframe): Update. Make "static const".
* ppcnbsd-tdep.c (tramp_frame ppcnbsd_sigtramp): Update.
