Represent new Linux syscalls for s390 and s390x in GDB's syscall info.
Add the syscalls from 355 (userfaultfd) up to 374 (mlock2) as well as
the previously reserved NUMA syscalls 268-270, 287, and 310.
gdb/ChangeLog:
* syscalls/s390-linux.xml: Add NUMA syscalls and new syscalls up
to 374.
* syscalls/s390x-linux.xml: Likewise.

Hi,
This patch is to support catch syscall on aarch64 linux. We
implement gdbarch method get_syscall_number for aarch64-linux,
and add aarch64-linux.xml file, which looks straightforward, however
the changes to test case doesn't.
First of all, we enable catch-syscall.exp on aarch64-linux target,
but skip the multi_arch testing on current stage. I plan to touch
multi arch debugging on aarch64-linux later.
Then, when I run catch-syscall.exp on aarch64-linux, gcc errors that
SYS_pipe isn't defined. We find that aarch64 kernel only has pipe2
syscall and libc already convert pipe to pipe2. As a result, I change
catch-syscall.c to use SYS_pipe if it is defined, otherwise use
SYS_pipe2 instead. The vector all_syscalls in catch-syscall.exp can't
be pre-determined, so I add a new proc setup_all_syscalls to fill it,
according to the availability of SYS_pipe.
Regression tested on {x86_64, aarch64}-linux x {native, gdbserver}.

2. The use of a single year range, instead of potentially multiple
