Compare of (`x`

< `y`

) || (`x`

> `y`

).

## Description

Returns the component-wise compare of (`x`

< `y`

)
|| (`x`

> `y`

).

## Notes

If an implementation extends this specification to support IEEE-754 flags or
exceptions, then all built-in relational functions shall proceed without raising the
`invalid`

floating-point exception when one or more of the operands
are NaNs.

The built-in relational functions are extended with
cl_khr_fp16 to
include versions that take half, and
half{2|3|4|8|16} as arguments.

The function returns a 0 if the specified relation is `false`

and a 1
if the specified relation is `true`

for scalar argument types. These
functions shall return a 0 if the specified relation is `false`

and a -
1 (i.e. all bits set) if the specified relation is `true`

for vector
argument types.

The function returns 0 if either argument is not a number (NaN).
