gallium: Add a cap bit for integer multiplication between 32-bit and 16-bit
Driver supports integer multiplication between a 32-bit integer and a
16-bit integer. If the second operand is 32-bits, the upper 16-bits are
ignored, and the low 16-bits are possibly sign extended as necessary.
Iris will eventually enable this. Not sure about other drivers.
v2: Add default value to u_screen.c. Suggested by Caio.
