Tom Stellard 3a9632d544 s/_CLC_DECL/_CLC_DEF/
Some function definitions were using _CLC_DECL, which meant that they
weren't being marked as always_inline.

Aaron Watry fbe439f8c0 Add mul_hi implementation [v2]
Everything except long/ulong is handled by just casting to the next larger type,
doing the math and then shifting/casting the result.

For 64-bit types, we break the high/low parts of each operand apart, and do
a FOIL-based multiplication.

v2:
  Discard the stack-overflow implementation due to copyright concerns.
  - The implementation is still FOIL-based, but discards the previous code.

Aaron Watry 8548725f29 Add rhadd builtin
rhadd = (x+y+1)>>1

Implemented as:
(x>>1) + (y>>1) + ((x&1)|(y&1))

This prevents us having to do assembly addition and overflow detection

Aaron Watry 7659157f1b Add hadd builtin
(x + y) >> 1 gets changed to:
(x>>1) + (y>>1) + (x&y&1)

Saves us having to do any llvm assembly and overflow checking in the addition.

Aaron Watry 1769b1fca9 Implement generic upsample()
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.

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

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

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.
