The multop instruction implicitly writes rtop which is not preserved
acrosss thread switches. We can spill the sources of the multop
(since these would happen before multop) and the destination of
umul24 (since that would happen after umul24).
Fixes some OpenCL tests when V3D_DEBUG=opt_compile_time is used to
choose a different compile configuration.
