  [TargetMachine] Simplify shouldAssumeDSOLocal by processing ExternalSymbolSDNode early

The function accrues many `GV` nullness checks. Process `!GV`
(ExternalSymbolSDNode) early to simplify code.

Also improve a comment added in r327198 (intrinsics is a subset of
ExternalSymbolSDNode).

Intended to be NFC.
