ispc/builtins/target-generic-common.ll
Matt Pharr 0d3993fa25 More varied support for constant vectors from C++ backend. 
If we have a vector of all zeros, a __setzero_* function call is emitted,
permitting calling specialized intrinsics for this.  Undefined values
are reflected with an __undef_* call, which similarly allows passing that
information along.

This change also includes a cleanup to the signature of the __smear_*
functions; since they already have different names depending on the
scalar value type, we don't need to use the trick of passing an
undefined value of the return vector type as the first parameter as
an indirect way to overload by return value.

Issue #317.
