    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.

    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).
