[3/4] 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.

I guess I said that before, but just in case I didn't: I would prefer if
this patch already updated the other architectures as well.  IIUC you
are planning to do that in another series of patches, but it would be
good if you did everything at once, I think.  However, I will not oppose
if you decide to touch only on x86_64 for now.

Other than that, I have only one comment.

This could be

  "\\\[${decimal}\\\]"

right?

This patch looks good to me (I am not the maintainer of this part of the
code).

Sergio,

Thank you for your review.  I applied your suggestions and I will send
the updated patches to this list in a few moments.

Updating the syscall files by hand is quite error-prone and requires
lots of typing.  Should we bring PR 14276 to the table, it would also
require extra work to update the groups later.

A few weeks ago, you and I talked about writing a script to fix PR14276.
What I want to do is to save me some typing now and update the other
architectures only after we have such script to generate the syscall
files, so we can use it to also generate the group information
automatically.  What do you think? Is that ok for you?

Yeah, I am aware of that :-/.

Heh, since you asked :-P...

My opinion is that writing this script could take some time, and I am
not counting on it be to ready soon, unfortunately.

That being said, I also don't think we should let the perfect be the
enemy of the good (I think Pedro said that once, and I liked the
phrase).  Therefore, I am OK with your patch as is, provided we don't
take too long to start working on this script :-).

Thanks,
