Add AArch64 HWCAPs from Linux 5.0.
This patch adds new AArch64 HWCAPs from Linux 5.0 to the AArch64
bits/hwcap.h and dl-procinfo.c.
Tested (compilation only) with build-many-glibcs.py for
aarch64-linux-gnu.
* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_SB): New
macro.
(HWCAP_PACA): Likewise.
(HWCAP_PACG): Likewise.
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT):
Increase to 32.
(_dl_aarch64_cap_flags): Add new entries for new HWCAPs.
