LOG: [TargetLowering] Remove comment above definition of TargetLowering::EmitInstrWithCustomInserter. NFC

This duplicates the documentation from the declaration, but has
gotten out of sync. There was a mention of a DenseMap that has
been gone for 14 years. Since this declaration is a default
implementation of a virtual function, its unlikely to be looked at.
Just remove it.
