There's a statement that intends to generate a 32-bit hashcode, but due
to integer promotion, the intermediate values can trigger signed integer
overflow, which is undefined behavior.
To avoid this, cast at least one operand to unsigned int before
multiplying, which will cause the result to be promoted to unsigned int
instead of signed int.
With this patch, I'm able to build core for qemu-x64 with host_asan-ubsan.
