Subject: [PATCH] Revert "[dxbc] Handle dead code in shader binaries"

Apparently this regressed something, but the reporter who asked
for this fix in the first place did not specify what, so let's
just revert this and break the whole thing again until we get
something to actually work with.

This reverts commit 5115d80d5179d0158fae270616ef764dacc464c9.
