win32.fpe test raises wrong trap natively on win8

_From [bruen...@google.com](https://code.google.com/u/109494838902877177630/) on September 19, 2012 22:24:37_

on win8 built with VS2012, win32.fpe run natively or under DR produces:

about to do longjmp
Error 141: Other floating point error

=>
#define _FPE_MULTIPLE_TRAPS 0x8d /\* on x86 with arch:SSE2 OS returns these exceptions */

instead of:

about to do longjmp
Error 131: Divide by zero

for now I will probably just make it pass and leave this issue open for
further investigation
