* doc/extend.texi: Document new behavior for pointers to arrays
with qualifiers.

(common-pointer-type): For pointers to arrays take qualifiers from
element type.
(build_conditional_expr): Add warnings for lost qualifiers.
(comp-target-types): Allow pointers to arrays with different qualifiers.
(convert-for-assignment): Adapt warnings for discarded qualifiers. Add
WARNING_FOR_QUALIFIERS macro and rename WARN_FOR_QUALIFIERS
to PEDWARN_FOR_QUALIFIERS.
c-family/
* c.opt (Wdiscarded-array-qualifiers): New option.
testsuite/
