* x86-64-tdep.c (X86_64_NUM_SAVED_REGS): Set to X86_64_NUM_GREGS.
(x86_64_sigtramp_frame_cache): Use `sc_reg_offset' to find saved
registers.
* x86-64-linux-tdep.c (x86_64_linux_sc_reg_offset): New variable.
(x86_64_linux_init_abi): Initialize TDEP->sc_reg_offset and
TDEP->sc_num_regs instead of TDEP->sc_pc_offset and
TDEP->sc_sp_offset.
