Occurances of CODE_CEXPR (x)
have been replaced by EXPRS_EXPR (CODE_CEXPRS (x))
to avoid confusion.
The traversals of CODE_CEXPR
in SSAWLI.c
and pad_transform.c
have been replaced by traversals of the entire CODE_CEXPRS
chain.
Let me know if this should instead still be a traversal of only the first EXPRS_EXPR
...
WLGRID_CEXPR
similarly has a confusing name. However it is not used anywhere so I just removed it.
