HexagonConstEvaluator::evaluateHexVector2: Added on July 28, 2016 in
commit 167d918225ecd05a63f6b8d449c317feda741e18 without a definition or
any callers.

August 27, 2024 in commit 8e901c255df45e38cb1d69a576804029e20868bf.
dsymutil::DwarfLinkerForBinary::createStreamer: The definition and
caller were removed on April 1, 2023 in commit
36f351098cd50809658493d9b2e22a795874bab0 (when the non-template
declaration in DwarfLinkerForBinary.h was replaced with a template
declaration without a definition).
exportCoverageDataToJson: The definition and caller were replaced with
CoverageExporterJson on January 4, 2018 in commit
1ef3a778ac47564aa5a7f04bbf572d22d1c616fb.
objdump::printCOFFFileHeader, objdump::printELFFileHeader, and
objdump::printWasmFileHeader: The definitions and callers were replaced
with Dumper::printPrivateHeaders on July 14, 2023 in commit
