I don't think this change is correct.  DECL_DECLARED_INLINE_P controls
linkage, and -fno-default-inline is documented as not changing linkage.
 Thus, the change that you're making might affect the linkage of inline
functions in object files, which would be bad.  The C++ front end sets
DECL_DECLARED_INLINE_P, but no DECL_INLINE, which seems exactly
consistent with the documentation: this function should be treated as
inline for linkage purposes, but the middle end should not try to inline it.
