Don't allow MSVC optimizer to make too many wrong assumptions about function pointer

The MSVC compiler is slightly confused about the jmp-call inside the __asm
block of the dynarec prologue. It will try to optimize the surrounding code and
ends up in overwritting the code function poiner with a sign extended version
of the lower 16 bit of code.

MSVC seems to be slightly more careful with void pointers
