Subject: ARMTargetParser: Make BSD Thumb/BE armv6 work
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=deae59fceb40f5036afec17435473177b9778cb1

ARMTargetParser: Make BSD Thumb/BE armv6 work

Simple change to make arch like "thumbv6" and "armbev6" to return the
correct CPU for FreeBSD and NetBSD.
