[PATCH] Rename BlackList class to GlobalList and move it to Transforms/Utils.

[Alexey Samsonov]

  Why do you need this? Blacklist actually modifies the codegen, disabling instrumentation for source files, functions, or global variables. I think the original name describes this role better.

  I'm OK with moving BlackList.cpp to lib/Transforms/Utils.
