Summary

Currently dead gc value mentioned in the deopt section are not listed in gc section
and so are processed separately.
With this CL all deopt gc values are considered as base pointers and processed in the
same way as other gc values.

The fact that deopt gc pointer is a base pointer was used all the time but
it is explicitly documented here by putting the value in SI.Base.

This is an alternative patch for D97108.
The idea of the patch comes from Philip Reames.
