Sema: Build a full ApplyExpr for ExprPattern ~= operators.

Sema knows better how to call getLogicValue to get an i1 from a conditional than SILGen does. Fake up a placeholder variable we can slot into a 'expr ~= var' expression, and have the type-checker run on the entire apply expr to generate getLogicValue() conversions on the applied result.
