Message:

VMM/IEM: Get rid of IEM_MC_STORE_SSE_RESULT(), by checking for pending exceptions with IEM_MC_MAYBE_RAISE_SSE_AVX_SIMD_FP_OR_UD_XCPT() before storing the actual result which can be done with IEM_MC_STORE_XREG_XMM(). Avoids the recompiler emitting code for checking the MXCSR twice, bugref:10641
