  [CIR] Fixup type of no-prototype functions when emitting an alias. (#212308)

If a function is first used through a no-prototype declaration, then
defined later as an alias, we erased the old declaration and created the
new one with the new type. However the earlier references still used the
old type, which caused a verification error.

This patch just makes sure we replace the uses of it similar to how we
do with a similar problem with normal functions.

Note: there is a bit of inconsistency in how we're setting the type of
the function between OGCG and CIR that I'm not sure of the impact of,
    but that is prexisting.
