dualfroz 3b5201cabc Fix #4153: Keep foreach when a named argument reads the loop variable
Once a named argument is hoisted, the call becomes a CallWithNamedArgs
block, and inlining moves the Current getter into the block's first
argument store. The foreach detection could not move it back out:
CanInlineIntoSlot refused the block, and for an instance call the store
of the 'this' argument in front counted as a write the getter cannot be
moved past. That store only writes the block's own variable, so the
getter is checked against the stored value instead, the same way
CanExtendNamedArgument allows inlining into that position.
