buffer tells fiddle to create a buffer of a number of bytes.

skip_to tells fiddle to skip to some new offset. It's essentially an
unnamed buffer

Fixed the issues where the output C code did not use correct register
sizes.

Now it includes information about the package a symobl is in. The object
its in and the register its in. This allows better code generation in
the backend that's somewhat more organized.

The compiler reset the offset to 0 in bitfield substructures.

This is for expressions which must be calculatable at compile time.

Have basic implementations down for coarse registers. Working on getting
bitfields supported.
