Reduces all vector upsamples down to its scalar components, so probably
not the most efficient thing in the world, but it does what the
spec says it needs to do.
Another possible implementation would be to convert/cast everything as
unsigned if necessary, upsample the input vectors, create the upsampled
value, and then cast back to signed if required.

libclc was defining and undefing GENTYPE and several other macros with
common names in its header files. This was preventing applications from
defining macros with identical names as command line arguments to the
compiler, because the definitions in the header files were masking the
macros defined as compiler arguements.

Assumes that the target supports byte-addressable stores.

libclc: Rename clz.ll to clz_if.ll to ensure it gets built.
configure.py treats files that have the same name with the .cl and .ll
extensions as overriding eachother.
E.g. If you have clz.cl and clz.ll both specified to be built in the same
SOURCES file, only the first file listed will actually be built.
Since the contents of clz.ll were an interface that is implemented in
clz_impl.ll, rename clz.ll to clz_if.ll to make sure that the interface is
built.

libclc: Add stub clz builtin

For any GENTYPE that isn't scalar, we need to implement a mixed
vector/scalar version of clamp/max.
This depends on the min() patches I sent to the list a few minutes ago.

Checks if the current GENTYPE is scalar, and if not, then defines a separate
implementation of the function which casts the second arg to vector before
proceeding.

This implementation does a lot of bit shifting and masking. Suffice to say,
this is somewhat suboptimal... but it does look to produce correct results
(after the piglit tests were corrected for sign extension issues).
Someone who knows LLVM better than I could re-write this more efficiently.
