LOG: [clang-tidy] Use DenseMap::insert_range (NFC) (#133844)

We can safely switch to insert_range here because
SyntheticStmtSourceMap starts out empty in the constructor.  Also
TheCFG->synthetic_stmts() comes from DenseMap, so we know that the
keys are unique.  That is, operator[] and insert are equivalent in
this particular case.
