[LLVMdev] MAJOR API CHANGE: LLVMContext

[Owen Anderson]

Notice of a major upcoming API change:  The static methods for  
constructing types and constants will be going away in the future.   
Instead, the global uniquing tables that lurk behind these APIs will  
be privatized within LLVMContext instances.

What this means for you:  Your client application will need to create  
an LLVMContext in main(), and pass it into a few APIs (the constructor  
for Module, for instance).  You can, in theory, have more than one  
LLVMContext as long as you never want Modules created under separate  
contexts to interact.

In the near term, I will be committing patches to do this conversion  
for the existing LLVM tools, including Clang and LLVM-GCC, which  
should provide examples for those following along at home.
