[ir] Use the const eval results for expressions. 

If an expression has a `sem::ValueExpression` attached we can use it to
directly obtain the result of the expression and stop emission. This Cl
updates the IR builder to pull the expression result if possible.

Several of the tests have been updated to go through a function in order
to stop const-eval from removing all the test content.
