Paul Berry 506ac7f953 Rework linker type inference using ExprBuilder. 
This CL changes the way linker type inference works.  Instead of
walking the operations in an UnlinkedExpr in order and inferring types
directly, it first builds an AST for the expression using ExprBuilder,
then uses ResolverVisitor to resolve the AST and perform type
inference.

This helps ensure that summary type inference and ordinary AST-based
type inference produce the same result, since they now use the same
core algorithm.  In particular, this means that summary type inference
now does downwards inference properly.

Since the ResolverVisitor makes greater use of the element model than
the rest of the linker, this required implementing additional methods
in the linker's element model.

This CL includes some minor fixes to ExprBuilder that were uncovered
during testing.  It also contains some minor changes to
ResolverVisitor to make it work during linking.

Fixes #32525.
Fixes #32394.
