Log:
Correct the patch table entries for the 64-bit intrinsic math
routines (_alldiv(), _allmul(), _alludiv(), _aullmul(), etc...)
that use the _stdcall calling convention.
These routines all take two arguments, but the arguments are 64 bits wide.
On the i386 this means they each consume two 32-bit slots on the stack.
Consequently, when we specify the argument count in the IMPORT_SFUNC()
macro, we have to lie and claim there are 4 arguments instead of two.
This will cause the resulting i386 assembly wrapper to push the right
number of longwords onto the stack.
This fixes a crash I discovered with the RealTek 8180 driver, which
uses these routines a lot during initialization.
