add CLIB_HAVE_VEC128 with NEON intrinsics (VPP-1127)
Enable CLIB_HAVE_VEC128 if both aarch64 and __ARM_NEON
ie. armv8 only, not armv7
Add more neon compare intrinsics wrappers.
I only add simple intrinsics wrappers. More complex ones can be added
later as they are needed, with performance tests on the corresponding
feature to back them up.
Remove wrongly added 128bits definitions defined on both armv7 and armv8
without concern for NEON instructions presence.
Notable correspondinf code activations:
* MHEAP_FLAG_SMALL_OBJECT_CACHE in mheap.c
* ip4 fib mtrie leaves access
* enable ixge plugin compilation for aarch64
(conf still disables it by default)
