This macro is currently unused, but I plan to use it shortly.
The previous form did casts of pointers without an address space, which

clang (since r280553) allows pointer casts in function overloads,
so we need to disambiguate the second argument.
clang might be smarter about overloads in the future
see https://reviews.llvm.org/D24113, but let's be safe in libclc anyway.

OpenCL 1.1+: "Returns y if y < x, otherwise it returns x. If x *or* y

The 1.0 version is stricter so use that one.

The float implementation is almost a direct port from the amd-builtins,
but instead of just having a scalar and float4 implementation, it has
a scalar and arbitrary width vector implementation.
The double scalar is also a direct port from AMD's builtin release.
The double vector implementation copies the logic in the float vector
implementation using the values from the double scalar version.
Both have been tested in piglit using tests sent to that project's
mailing list.

The macro names given in the following list must use the values
specified. The values shall all be constant expressions suitable
for use in #if preprocessing directives.
