COFF: Add /alternatename option. Previously, this feature was implemented using a special type of undefined symbol, in addition to an intricate way to make the resolver read a virtual file containing that renaming symbols. Now the feature is directly handled by the symbol table. The symbol table has a function, rename(), to rename symbols, whose definition is 4 lines long. Symbol renaming is naturally modeled using Symbol and SymbolBody. llvm-svn: 238696

COFF: Fix logic to find default entry name or subsystem. The previous logic to find default entry name or subsystem does not seem correct (i.e. was not compatible with MSVC linker). Previously, default entry name was inferred from CRT functions and user-defined entry functions. Subsystem was inferred from CRT functions. Default entry name and subsystem are now inferred based on the following table. Note that we no longer use CRT functions to infer them.

COFF: Don't add new undefined symbols for /alternatename. Alternatename option is in the form of /alternatename:<from>=<to>. It's effect is to resolve <from> as <to> if <from> is still undefined at end of name resolution. If <from> is not undefined but completely a new symbol, alternatename shouldn't do anything. Previously, it introduced a new undefined symbol for <from>, which resulted in undefined symbol error. llvm-svn: 240161

COFF: Allow identical alternatename options. Alternatename option is in the form of /alternatename:<from>=<to>. It is an error if there are two options having the same <from> but different <to>. It is *not* an error if both are the same. llvm-svn: 240075
