'{ a, b, c }' - Represents an initializer for a BitsRecTy value.

It contains a vector of bits, whose size is determined by the type.

Is this a concrete and fully resolved value without any references or stuck operations?

Unset values are concrete.

◆ resolveReferences()

This function is used by classes that refer to other variables which may not be defined at the time the expression is formed.

If a value is set for the variable later, this method will be called on users of the value to allow the value to propagate out.
