Includes a temporary bugfix for popcnt with 32-bit operand. The popcnt issue was initially identified by Benjamin Bouvier <public@benj.me>, and the root cause was debugged by Joey Gouly <joey.gouly@arm.com>. This patch is simply a quick fix that zero-extends the operand to 64 bits; Joey plans to contribute a more permanent fix shortly (tracked in #1537).
