  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.

	* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_DIT): New
	macro.
	(HWCAP_USCAT): Likewise.
	(HWCAP_ILRCPC): Likewise.
	(HWCAP_FLAGM): Likewise.

dl-procinfo.c needs to be updated too.

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