* cobgen.c, field.c, tree.c, tree.h, typeck.c: Hand merge 2015-07-02
about COMP-X.
* cobgen.c (output_size): use `compx_size` when usage is COMP-X
* cobgen.c (output_attr): override type to `COB_TYPE_NUMERIC_BINARY`
when usage is `COMP-X`
* field.c: Increment `pic_digits` values by one
* field.c (setup_parameters): set the `compx_size` and override usage
of `COMP-N` to `COMP-X` field when picture starts with `X`
* field.c (compute_size): leave `align_size` to 1 when usage is
`COMP-x` and use `compx_size` to compute size of `COMP-X`
* tree.c (cb_tree_category): `COMP-X` is of category
`CB_CATEGORY_NUMERIC`.
* tree.c (cb_field_size): size of `COMP-X` field and references is
`compx_size`
* tree.h (struct cob_field): add `compx_size` to `cob_field`
* typeck.c (cb_check_numeric_name): `COMP-X` is numeric name
* typeck.c (cb_check_numeric_edited_name): `COMP-X` is numeric edited
name
* typeck.c (validate_move): `COMP-x` is validated when dst is category
`ALPHANUMERIC` or `ALPHANUMERIC-EDITED`.

Couldn't we just use f->pic->size for this rarely used definition, instead of adding an extra field to all variables?
