Bjorn Steinbrink 0cb6d37dea Remove conflicting attributes before adding deduced readonly/readnone
Summary:
In case of functions that have a pointer argument and only pass it to
each other, the function attributes pass deduces that the pointer should
get the readnone attribute, but fails to remove a readonly attribute
that may already have been present.
