Initial infrastructure for arbitrary precision integer
codegen support. This should have no effect on codegen for other types. Debatable bits: (1) the use (abuse?) of a set in SDNode::getValueTypeList; (2) the length of getTypeToTransformTo, which maybe should be refactored with a non-inline part for extended value types. llvm-svn: 43030
