'char' is unsigned on all ARM and Thumb architectures. Clang gets this

option, but gets it wrong for thumb triples. This fixes that.

Various tests had sprung up over the years which had --check-prefix=ABC on the
RUN line, but "CHECK-ABC:" later on. This happened to work before, but was
strictly incorrect. FileCheck is getting stricter soon though.
