My changes to get_narrower to support COMPOUND_EXPRs apparently
used a wrong type for the COMPOUND_EXPRs, while e.g. the rhs
type was unsigned short, the COMPOUND_EXPR got int type as that was the
original type of op. The type of COMPOUND_EXPR should be always the type
of the rhs.

* tree.c (get_narrower): Use TREE_TYPE (ret) instead of
TREE_TYPE (win) for COMPOUND_EXPRs.
