<pre>I found this issue doing some random code generation testing on trunk. Here's
a reduced IR example:
---------------- >8 ----------------
target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128"
target triple = "x86_64-pc-win32"
@"\01?id2710@@3U__m128d@@A" = global <2 x double> zeroinitializer, align 16
@"\01?id2729@@3U__m128d@@A" = global <2 x double> zeroinitializer, align 16
; Function Attrs: nounwind readnone
define <2 x i32> @"\01?test80@@YAT__clang_vec2_J@@XZ"() #0 {
entry:
%id2709 = alloca i32, align 4
%id2718 = alloca i32, align 4
%id2708 = alloca <2 x i32>, align 8
%0 = load <2 x double>* @"\01?id2710@@3U__m128d@@A", align 16
%1 = load <2 x double>* @"\01?id2710@@3U__m128d@@A", align 16
%2 = call i32 @llvm.x86.sse2.comilt.sd(<2 x double> %0, <2 x double> %1)
store i32 %2, i32* %id2709, align 4
%3 = load <2 x double>* @"\01?id2710@@3U__m128d@@A", align 16
%4 = load <2 x double>* @"\01?id2729@@3U__m128d@@A", align 16
%5 = call i32 @llvm.x86.sse2.comilt.sd(<2 x double> %3, <2 x double> %4)
store i32 %5, i32* %id2718, align 4
%6 = load i32* %id2709, align 4
%7 = load i32* %id2718, align 4
%8 = insertelement <2 x i32> undef, i32 %6, i32 0
%9 = insertelement <2 x i32> %8, i32 %7, i32 1
%10 = bitcast <2 x i32> %9 to x86_mmx
%11 = bitcast x86_mmx %10 to <2 x i32>
store <2 x i32> %11, <2 x i32>* %id2708, align 8
%12 = load <2 x i32>* %id2708, align 8
ret <2 x i32> %12
}
; Function Attrs: nounwind readnone
declare i32 @llvm.x86.sse2.comilt.sd(<2 x double>, <2 x double>) #0
attributes #0 = { nounwind readnone }

and for reference here is the original C++ testcase:
---------------- >8 ----------------
