This was previously implemented with a macro and we were using
__builtin_copysign(), which takes double inputs for the float
version of copysign().

relational.h includes relational macros for defining functions which need to
return 1 for scalar true and -1 for vector true.
I believe that this is the only place that this behavior is required, so the
macro is placed at its lowest useful level (same directory as it is used in).
This also creates re-usable unary/binary declaration and floatn includes which
should simplify relational builtin declarations.
Mostly patterned off of include/math/[binary_decl|unary_decl|floatn].inc
but with required changes for relational functions.

Otherwise the test evaluates to true on OpenCL 1.1 and earlier. Since we
therefore cannot use the CL_VERSION_?_? macros move them to the proper
position in the top-level header.

These are apparently only defined in OpenCL 1.2.
HALF_MAX, HALF_MIN and HALF_EPSILON are currently omitted. Clang does
not seem to support the ‘h’ suffix for half float constants even with
the cl_khr_fp16 extension enabled.

This doesn't work yet, but it was agreed to commit as-is with the logic
that "broken" is better than "completely missing" and this should be
fixed in clang.

OpenCL C lang says that trunc rounds towards zero.
llvm.trunc.* intrinsic rounds to integer not larger in magnitude.
These definitions are equivalent.
