[turbofan] Properly delete nodes in the GraphReducer.

This is required to enable a value numbering reducer, which needs to be
able to recognize "dead nodes".

Add missing -Wno-missing-field-initializer flag to standalone.gypi.

Chrome uses -Wno-missing-field-initializers when building V8, so we
should better use that as well. It silences warnings generated for the
GTest port files.

Make Operator const-correct in preparation for allocating sharing
