[ARM] Consistently check for neon in vect effective targets

Conditions checked for ARM targets in vector-related effective targets
are inconsistent:

* sometimes arm*-*-* is checked
* sometimes Neon is checked
* sometimes arm_neon_ok and sometimes arm_neon is used for neon check
* sometimes check_effective_target_* is used, sometimes
* is-effective-target

This patch consolidate all of these check into using is-effective-target
arm_neon and when little endian was checked, the check is kept.
