ARM assembly syntax uses @ for a comment, execpt for the second parameter of the .symver directive which requires @ as part of the symbol name. This commit fixes the parsing of this directive by adding a special case for ARM for this one argumnet. To make the change we had to move the AllowAtInIdentifier variable to the MCAsmLexer interface (from AsmLexer) and expose a setter for the value. The ELFAsmParser then toggles this value when parsing the second argument to the .symver directive for a target that uses @ as a comment symbol git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199339 91177308-0d34-0410-b5e6-96231b3b80d8
