The Linker interface has some dead code after the cleanup in r172749

2013-03-19T15:26:24Z

(and possibly others). The attached patch removes it, and tries to update comments accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177406 91177308-0d34-0410-b5e6-96231b3b80d8

Add static cast to unsigned char whenever a character classification function is called with a signed char argument, in order to avoid assertions in Windows Debug configuration.

[Linker] Kill Linker::LoadObject which is dead, and drop the BitReader dependency again.

The IR linker still depends on the bitcode reader.

[Linker] Drop some now-dead component dependencies.

[Linker] Drop support for IR-level extended linking support (archives, etc.).

2013-01-17T19:52:25Z

- This code is dead, and the "right" way to get this support is to use the platform-specific linker-integrated LTO mechanisms, or the forthcoming LLVM linker. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172749 91177308-0d34-0410-b5e6-96231b3b80d8

[IR] Add 'Append' and 'AppendUnique' module flag behaviors.
