pan/midgard: Count shader-db stats by bundled instructions

This does not affect shaders in any way. Rather, it makes the shader-db
instruction count recorded in the compiler accurate with the in-order
scheduler, matching up with what we calculate from pandecode.

Though shaders are the same, instruction counts cannot be compared
across this commit for this reason.
