Subject: parsergen: rearrange 'struct state' to reduce wastage.
X-Git-Url: https://ocean-lang.org/code/?p=ocean;a=commitdiff_plain;h=4e76641ba6fa31b2cafb16b2452f585ba70a6822

parsergen: rearrange 'struct state' to reduce wastage.

Having a pointer between two shorts results in a lot of empty space
in the struct.  Remove this wastage.
