File pkg/compiler/lib/src/cps_ir/cps_ir_builder.dart (right):

https://codereview.chromium.org/1128903012/diff/1/pkg/compiler/lib/src/cps_ir...
pkg/compiler/lib/src/cps_ir/cps_ir_builder.dart:1870: catchContinuation.body =
catchBuilder._root;
The fragment in catchBuilder was previously lost in the void.

pkg/compiler/lib/src/cps_ir/cps_ir_builder.dart:2487: return addPrimitive(new
ir.GetMutableVariable(getMutableVariable(local)));
This is independent of the other change.
