Moves the alloc_dbginfo type to Debuginfo, to avoid a circular
dependency on architectures that use Branch_relaxation.
This commit generates frame tables with allocation sizes on all
architectures, but does not yet update the allocation code for
non-amd64 backends.
Separate the description of the IR from the transformations
performed on it by moving type declarations from linearize.ml
into their own file, called linear.ml.
