Remove NEXT_OPCODE calls within embedded while-loops

I think I found the problem: NEXT_OPCODE translates to a simple "continue"
statement under MSVC (there's no computed goto). As a result, you can't
use NEXT_OPCODE within an embedded while-loop, as it will wrongly jump
to the nearest while-loop. I found 2 occurrences of this problem. Patch
attached. The patch is not very elegant, but it works.
