[FFmpeg-devel] [PATCH 2/2] aarch64: vp9 16bpp: Fix assembling with Xcode 6.2 and older

From: Memphiz <memphis at machzwo.de>

Properly use the b.eq form instead of the nonstandard form (which
both gas and newer clang accept though), and expand the register
lists that used a range (which the Xcode 6.2 clang, based on clang
3.5 svn, didn't support).
