Allow aliases to be unnamed. If globals can be unnamed, there is no reason for aliases to be different. The restriction was there since the original implementation in r36435. I can only guess it was there because of the old bison parser for the old alias syntax. llvm-svn: 239921

AsmParser: Make the code for parsing unnamed aliases more closely resemble that for unnamed globals. This fixes parsing of forward references to unnamed aliases. While here, remove an unnecessary isa check. llvm-svn: 254054
