Respect matrix orientation when doing store to raw buffer

[vcsharma]

Notice that even with /Zpc flag, we store {1, 2, 3, 4} to the raw buffer instead of {1, 3, 2, 4}

cmd: dxc.exe /E main /T vs_6_5 /Zpc

RWByteAddressBuffer buffer;

void main()
{
	float2x2 t = {1,2,3,4};
	buffer.Store(0, t);
}

target datalayout = "e-m:e-p:32:32-i1:32-i8:32-i16:32-i32:32-i64:64-f16:32-f32:32-f64:64-n8:16:32:64"
target triple = "dxil-ms-dx"

%dx.types.Handle = type { i8* }
%struct.RWByteAddressBuffer = type { i32 }

define void @main() {
  %1 = call %dx.types.Handle @dx.op.createHandle(i32 57, i8 1, i32 0, i32 0, i1 false)  ; CreateHandle(resourceClass,rangeId,index,nonUniformIndex)
  call void @dx.op.rawBufferStore.f32(i32 140, %dx.types.Handle %1, i32 0, i32 undef, float 1.000000e+00, float 2.000000e+00, float 3.000000e+00, float 4.000000e+00, i8 15, i32 4)  ; RawBufferStore(uav,index,elementOffset,value0,value1,value2,value3,mask,alignment)
  ret void
}
