    make sources coretypes.h and tree.h clean

    The following removes HOWEVER_GCC_DEFINES_TREE and the alternate
    definition of tree from symbols.h and instead ensures that both
    coretypes.h and tree.h are included where required.  This required
    putting GCCs own 'NONE' in a scoped enum (see separate patch) and
    renaming the cobol use of UNSIGNED, SIGNED and BLOCK which conflict
    with enums from tree.h.

    There's a few things in conflict with options.h defines, notably
    cobol_dialect and cobol_exceptions but also yy_flex_debug (wherever
    that comes from).  I've chosen to simply #undef those where
    appropriate.  I've refrained from putting the coretypes.h and
    tree.h includes in cobol-system.h since not all files require this.

    This helps in making use of real.h instead of using _Float128.
