ACPICA: iASL: Enhancement for constant folding.
ACPICA commit 4f9e950d41cd6f6c704d5d6cf518647620d65e99
Add support to fold expressions with a target operand -- these are
folded and converted to a Store operator:
Add (4, 3, INT1) --> Store (7, INT1)
Also supports ASL+ constructs:
INT1 = 4 + 3 --> Store (7, INT1)
Linux kernel is not affected by this patch.
