This adds a new SystemZ-specific intrinsic, llvm.s390.tdc.f(32|64|128), which maps straight to the test data class instructions. A new IR pass is added to recognize instructions that can be converted to TDC and perform the necessary replacements. Differential Revision: http://reviews.llvm.org/D21949 llvm-svn: 275016
