Tom Stellard d768ac0395 Add __CLC_ prefix to all macro definitions in headers
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.

Tom Stellard 64b3bbae1e libclc: Add assembly versions of vstore for global [u]int4/8/16
The assembly should be generic, but at least currently R600 only supports
32-bit stores of [u]int1/4, and I believe that only global is well-supported.

R600 lowers the 8/16 component stores to multiple 4-component stores.

The unoptimized C versions of the other stuff is left in place.

Tom Stellard 922ac056e3 libclc: Add assembly versions of vload for global int4/8/16
The assembly should be generic, but at least currently R600 only supports
32-bit loads of int1/4, and I believe that only global is well-supported.

R600 lowers the 8/16 component vectors to multiple 4-bit loads.

Tom Stellard e78344dfae libclc: Implement clz() builtin
Squashed commit of the following:

commit a0df0a0e86c55c1bdc0b9c0f5a739e5adef4b056

    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: llvm assembly implementation of clz

    Untested... currently crashes in the same manner as add_sat.

    libclc: Add stub clz builtin

    For scalar int/uint, attempt to use the clz llvm builtin.. for all others
    return 0 until an actual implementation is finished.

Tom Stellard 34f513df7c libclc: Add clamp(vec, scalar, scalar) and max(vec, scalar)
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.

Tom Stellard 075b31a2fa libclc: Implement the min(vec, scalar) version of the min builtin.
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.

Tom Stellard 29b5b9816b libclc: Rename [add|sub]_sat.ll to [add|sub]_sat_if.ll
configure.py allows overloading *.cl with *.ll, but will only ever build
the first file listed in SOURCES of ${file}.cl and ${file}.ll

add_sat, sub_sat, (and the soon to be submitted clz) all define interfaces in
${function_name}.ll which are implemented in ${function_name}_impl.ll.

Renaming the interface files is enough to get them to build again, fixing
CL usage of these functions.

Tested on clover/r600g.

Tom Stellard 0bb381eaec libclc: implement rotate builtin
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.
