extend cache_integer_cst
This modules-related patch extends cache_integer_cst. Currently, when
given a small cst, that cst is added to the type's small and /must
not/ already be there. Large values are fine if they are already in
the large cache. This adds a parameter to indicate small duplicates
are ok, and it returns the cached value -- either what was already
tehre, or the newly inserted const.
gcc/
* tree.h (cache_integer_cst): Add defaulted might_duplicate parm.
* tree.c (cache_integer_cst): Return the integer cst, add
might_duplicate parm to permit finding a small duplicate.
