ELF: Do not ICF sections named with a C identifier. A user program may enumerate sections named with a C identifier using __start_* and __stop_* symbols. We cannot ICF any such sections because that could change program semantics. Differential Revision: https://reviews.llvm.org/D47242 llvm-svn: 333054 2018-05-23 10:14:28 +08:00			`# REQUIRES: x86`
