Linux 4.17 adds four new AArch64 hwcap values. This patch adds them
to glibc's AArch64 bits/hwcap.h.
Tested with build-many-glibcs.py for aarch64.

i think it's better if that's in the same commit.
(i should probably add a comment in hwcap.h about this)

Thanks, here's an updated patch.
Add AArch64 hwcap values from Linux 4.17.
Linux 4.17 adds four new AArch64 hwcap values. This patch adds them
to glibc's AArch64 bits/hwcap.h, with corresponding dl-procinfo.c
updates.
Tested with build-many-glibcs.py for aarch64.

* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT):
Increase to 28.
(_dl_aarch64_cap_flags): Add new flag names.
