ARM: simplify test. The test's DWARF stubs were there just to trigger the emission of .cfi directives. Fortunately, the NetBSD ABI already demands proper DWARF unwind info, so it's easier to just use that triple. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222055 91177308-0d34-0410-b5e6-96231b3b80d8

[ARM] Use symbolic register names in .cfi directives only with IAS (PR19110) This is a follow-up to r203635. Saleem pointed out that since symbolic register names are much easier to read, it would be good if we could turn them off only when we really need to because we're using an external assembler.
