compiler: track placeholder pointer types for conversion
We recently started walking through the hash table of pointer types to
finalize them. Unfortunately it is possible to create a new pointer
type while finalizing an existing one (test case: test/fixedbugs/issue5291)
and that breaks the iteration. So, instead, keep a list of
placeholder pointer types, and iterate through them while permitting
the list to be extended as we go.
