0c1c33b2f5 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/bits/hwcap.h (HWCAP_DIT): New
	macro.
	(HWCAP_USCAT): Likewise.
	(HWCAP_ILRCPC): Likewise.
	(HWCAP_FLAGM): Likewise.
	* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT):
	Increase to 28.
	(_dl_aarch64_cap_flags): Add new flag names.

This patch updates the aarch64 bits/hwcap.h and dl-procinfo.c for the
new HWCAP_ASIMDFHM value in Linux 4.16.

Tested with build-many-glibcs.py for aarch64-linux-gnu.

	* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_ASIMDFHM):
	New macro.
	* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT):

953c49cc3b aarch64: Update bits/hwcap.h for Linux 4.15. 
Define new HWCAP bits and add their name to dl-procinfo.c following
the linux definitions. Synchronizing with v4.15-rc8 version of linux,
these are not expected to change before the 4.15 release.

	* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_SHA3): Define.
	(HWCAP_SM3, HWCAP_SM4, HWCAP_ASIMDDP, HWCAP_SHA512, HWCAP_SVE): Define.
	* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c
	(_dl_aarch64_cap_flags): Update.
	(_DL_HWCAP_COUNT): Update.

afce1991f6 aarch64: make HWCAP updates less error prone 
Remove unused _DL_HWCAP_LAST definition and move _DL_HWCAP_COUNT
where it is needed (dl-procinfo.h always includes dl-procinfo.c).

	* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.h
	(_DL_HWCAP_LAST): Remove.
	(_DL_HWCAP_COUNT): Move to ...
	* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c
	(_DL_HWCAP_COUNT): ... here.

ea01a4da21 aarch64: Add hwcap string routines 
Add support for routines in dl-procinfo.h to show string versions of
HWCAP entries when a program is invoked with the LD_SHOW_AUXV
environment variable set and also to aid in path resolution for
ldconfig.
