Migrate the x86 MPX handle_segmentation_fault hook to report_signal_info.
gdb/ChangeLog:
* amd64-linux-tdep.c (amd64_linux_init_abi_common): Use
i386_linux_report_signal_info instead of
i386_linux_handle_segmentation_fault.
* i386-linux-tdep.c (i386_linux_handle_segmentation_fault): Rename
to i386_linux_report_signal_info and add siggnal argument.
(i386_linux_init_abi): Use i386_linux_report_signal_info instead
of i386_linux_handle_segmentation_fault.
* i386-linux-tdep.h (i386_linux_handle_segmentation_fault): Rename
to i386_linux_report_signal_info and add siggnal argument.
