compiler: Make empty interface types for vars during parse time.

    When making the type for a variable with an empty interface type,
    the parser makes an interface type with a NULL method set and relies
    on later passes to correct this.

    For sink variables, which are ignored in later passes, the interface
    method table is never finalized and a compile time assertion is issued.
    Instead, the initial type generated by the parser should be the empty
    interface type.

    Fixes golang/go#11579.

Refactor graphite-isl-ast-to-gimple.c

Refactor so that each function can access 'region'. This will help
maintain a parameter rename_map within a region. No functional change intended.
This patch will be followed by another set of patches
where translate_isl_ast_to_gimple::region is used to keep parameters which need
renaming. Since we are planning to remove limit_scops, we now have to maintain a
set of parameters which needs renaming. This refactoring helps avoid passing
`region' to all the functions in this file.
