Detailed Description

This is how we define the location of the CFA. We use to handle it
as REG + OFFSET all the time,  but now it can be more complex.
It can now be either REG + CFA_OFFSET or *(REG + BASE_OFFSET) + CFA_OFFSET.
Instead of passing around REG and OFFSET, we pass a copy
of this structure.
