    [fullcodegen] Implement operand stack depth tracking. · 38915ed7
    mstarzinger authored
    This implements a mechanism to track the exact depth of the operand
    stack in full-codegen for every sub-expression visitation. So far we
    only tracked the depth at statement level, but not at expression level.
    With the introduction of do-expressions it will be possible to construct
    local control flow (i.e. break, continue and friends) that target labels
    at an arbitrary operand stack depth, making this tracking a prerequisite
    for full do-expression support.
