a28e5f21d3 [ThinLTO] Fix assertions on lazy-loading of Metadata TBAA attachments 
Summary:
The issue happens with:

 %0 = ....., !tbaa !0
 %1 = ....., !tbaa !1

With !0 that references !1.

In this case when loading !0 we generates a temporary for the
operand !1. We now flush it immediately and trigger the load of
!1 before moving on. If we don't we get the temporary when
attaching to %1. This is usually not an issue except that we
eagerly try to update TBAA MDNodes, which is obviously not possible
if we only have a temporary.
