check register indexes during linking

Can you try this patch?  It adds checking to the linker to see if any
hardware/driver limits are exceeded.

This isn't ideal, however.  Since register allocation is the driver's job now,
the number of Mesa temp registers used may exceed the
gl_program_constants::MaxTemps value but be reduced to a smaller set of temps
in the driver.  The linker should call into the driver during linking to give
the driver a chance to check/report resource-exceeded errors.
