[LLD][ThinLTO] Handle GUID collision in import global processing
Summary:
If there are a GUID collision between two globals checking the
summarylist from the import index to make assumption can be dangerous.
Do not assume that a GlobalValue that has a GlobalVarSummary
actually is a GlobalVariable as it can be another GlobalValue with
the same GUID that the summary is connected to.
