Milad Farazmand 60a581eb48 PPC/s390: [lite] Allocate FeedbackCell arrays for create closures in lite mode 
Port 4237fc378c

Port 71c66873d6

Original Commit Message:

    We want to allocate feedback vectors lazily in lite mode. To do that,
    we should create closures with the correct feedback cell. This cl
    allocates feedback cell arrays to hold these feedback cells in lite mode.
    This cl also modifies the compile lazy to builtin to expect these arrays
    in the feedback cell.

    Drive-by fix: InterpreterEntryTrampoline no longer has argument count in
    a register. So updated comments and removed unnecessary push/pop of this
    register.
