Found while testing UBO loads in scenarios like this:
(assign (x) (var_ref vec_ctor)
(expression float d2f
(expression double ubo_load (constant uint (0)) (constant uint (0)))))
Without this patch, the src expression of d2f would be evaluated to a bitsize
of 32, which is not correct and would hit an assert in nir_validate.
