While in long-term it might be good to make DECL_VALUE_EXPR a
debuginfo only thing in short term the better approach would be to
have a special gimplifier state that turns on DECL_VALUE_EXPR
treatment (which would be off by default and thus during
force_gimple_operand).

The documentation of DECL_VALUE_EXPR should be adjusted
accordingly of course.
