  [MLIR][EmitC] Fix bug in EmitC form-expressions pass (#91084)

An `emitc.expression` can only yield a single result, but some
operations which have the `CExpression` trait can have multiple results,
which can result in a crash when applying the `fold-expressions` pass.
This change adds a check for the single-result condition and a simple
test.
