PR modula2/116181 Use GCC tree location_t and separate pointer types

This patch fixes all remaining -Wodr warnings in the modula-2 front end.
It removes the m2 Tree and m2 Location definitions and uses tree and
location_t throughout.  This allows the bootstrap tool mc to pick up the
GCC definitions for these data types (for the C translation of m2 sources).

The patch introduces a new module CDataTypes which contain two pointer
types: CharStar and ConstCharStar.  These map onto their C counterparts
when processed by mc however currently gm2 treats them as ADDRESS.
It might be sensible to have the gm2 versions of these data types
implemented though a builtin module in the future.
