Add $size() function. At the moment it works only on expressions, not on memories.

extract_reduce now only removes the head of the chain, relying on "clean" to delete upstream cells. Added "-allow-off-chain" flag, but it's currently ignored.

extract_reduce: Fix segfault on "undriven" inputs
...
This is easily triggered when un-techmapping if the technology-specific
cell library isn't loaded. Outputs of technology-specific cells will be
seen as inputs, and nets using those outputs will be seen as undriven.
Just ignore these cells because they can't be part of a reduce chain
anyways.
