[Sparc] Do not depend on icc for ta 1 The ta instruction will always trap, regardless of the value of the integer condition codes. TRAPri is marked as using icc, so we cannot use a pattern for TRAPri to implement ta 1, as verify-machineinstrs can complain that icc is not defined. Instead we implement ta 1 the same way as ta 5. llvm-svn: 337236
