this is the only unused command line option. There are some really dumb ones we should move out, but that is later.

Make AppendIterator a subclass of IteratorIterator

They seem to have no sharable code, and nothing in common beyond the interface they both already implement, but php5 does this.

Eliminate m_entryFP from ExecutionContext::m_nestedVMs

ExecutionContext::m_nestedVMs is a vector of saved state of nested
VMs (excluding the one that is currently running). This state contains
firstAR field pointing to the ActRec the corresponding VM was entered
at. In addition, m_nestedVMs contains m_entryFP pointing to the ActRec
of the VM we entered into at the time the m_nestedVM record was created.
This is redundant to the firstAR field (the data are shifted by one
index) and this diff eliminates it.

Move all VM state preservation responsibility to {push,pop}VMState()

Currently, the responsibility of preserving the previous VM state is
spread across multiple places. Move all relevant code to
{push,pop}VMState() and do it early before invoke*() methods get a
chance to modify the stack.
