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.

Assumes that the target supports byte-addressable stores.

Completely unoptimized.

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.
