[RFC,3/3] Create syscall groups for x86_64.

  This commit introduces the following syscall groups for the x86_64
architecture: memory, ipc, process, descriptor, signal and file.

Please note that the sorting of the syscalls among these several groups
follows the same structure used in strace.

This also introduces tests for catching groups of syscalls on the x86_64
architecture.

gdb/syscalls/

	* amd64-linux.xml: Add 'groups' attribute to several syscalls on
	x86_64.  Create groups memory, ipc, file, descriptor, process
	and signal.

gdb/testsuite/

	* gdb.base/catch-syscall.exp (do_syscall_tests): Add call
	to test_catch_syscall_group.
	(test_catch_syscall_group): New.

Thanks for the patch.

One thing I am planning to do is to create some kind of semi-automatic
script to extract the syscall info from Linux headers.  This
reorganization would make things harder in this area, so I propose that
you just include the group information to each syscall, without
modifying the current order.

gdb/syscalls doesn't have a ChangeLog file, so your ChangeLog entry will
have to be included in the gdb/ChangeLog file, and will have to refer to
syscalls/amd64-linux.xml.
