Form a denotation by conjoining with denotation that.
NoDenotations are dropped. MultiDenotations are handled by merging parts with same signatures. SingleDenotations with equal signatures are joined as follows:
In a first step, consider only those denotations which have symbols
that are accessible from prefix pre.
If there are several such denotations, try to pick one by applying the following three precedence rules in decreasing order of priority:
If there is exactly one (preferred) accessible denotation, return it.
If there is no preferred accessible denotation, return a JointRefDenotation
with one of the operand symbols (unspecified which one), and an info which
is the intersection (using & or safe_& if safeIntersection is true)
of the infos of the operand denotations.
If SingleDenotations with different signatures are joined, return NoDenotation.

Produce a denotation that is valid for the given context.
Produce a denotation that is valid for the given context. Usually called when !(validFor contains ctx.period) (even though this is not a precondition). If the runId of the context is the same as runId of this denotation, the right flock member is located, or, if it does not exist yet, created by invoking a transformer (@See Transformers). If the runId's differ, but this denotation is a SymDenotation and its toplevel owner class or module is still a member of its enclosing package, then the whole flock is brought forward to be valid in the new runId. Otherwise the symbol is stale, which constitutes an internal error.

Drops package objects. Represents terms in the owner chain by a simple ~.
(Note: scalac uses nothing to represent terms, which can cause name clashes
between same-named definitions in different enclosing methods. Before this commit
we used $' but this can cause ambiguities with the class separator '$').
A separator "" means "flat name"; the real separator in this case is "$" and
enclosing packages do not form part of the name.
