This is not a problem here
if only for PHI placement, we may get rid of this `use` here.
But as the comment said, it is useful if we are going to do code generation

Merge def and gen sets
For live-variable analysis it does not matter if def includes
variables that are previously use in the same block, the data flow
equations still have the same result. As such there is no need to
compute separate gen & def sets.
I'm keeping the name "def", because use of "gen" in this context is
pretty confusing (gen is usually the use set, not the def set).

Respect RC_INFERENCE during DFG construction
To avoid inserting phis that are only relevant with rc inference
enabled. Suprisingly, this affects only 0.8% of phis.

Fix SSA for ZEND_YIELD
Yield-by-ref defs a ref var, yield-by-var only defs an rc1/rcn var
if rc inference is used.
Also move BIND_LEXICAL where it belongs in DFG construction.

Introduce BIND_LEXICAL
This opcodes inserts a local CV into the closure static variable
table. This replaces the previous mechanism of having static
variables marked as LEXICAL, which perform a symtable lookup
during copying.
This means a) functions which contain closures no longer have to
rebuild their symtable (better performance) and b) we can now track
used variables in SSA.

Don't reuse SSA var in UNSET_VAR
Instead use the SSA var that UNSET_VAR actually defines. Otherwise
we get issues trying to DCE unsets.
