Type manager will construct a map of types gradually from
instructions.

Change the interfaces of in-memory representation to use pointers.
...
Previously we use vectors of objects and move semantics to handle
ownership. That approach has the flaw that inserting an object into
the middle of a vector, which may trigger a vector reallocation,
can invalidate some addresses taken from instructions.
Now the in-memory representation internally uses vector of unique
pointers to handle ownership. Since objects are explicitly heap-
allocated now, pointers to them won't be invalidated by vector
resizing anymore.

Dead constant elimination
...
A pass to remove dead constants, including both front-end constants and spec
constants.
This pass does not handle dead variables and types.
