Changeset 104183 in vbox for trunk/src/VBox/VMM/testcase

Message:

VMM/IEM: Get rid of IEM_MC_IF_MXCSR_XCPT_PENDING() and IEM_MC_RAISE_SSE_AVX_SIMD_FP_OR_UD_XCPT() and replace with IEM_MC_MAYBE_RAISE_SSE_AVX_SIMD_FP_OR_UD_XCPT(). This makes the microcode blocks leaner and the recompiler doesn't has to do as much state keeping. Furthermore there is now exactly one way of doing SSE/AVX floating point operations when it comes to exception handling, bugref:10641
