[lldb-dev] [RFC] Adding a clang-style LLVM.h (or, "Are you tired of typing 'llvm::' everywhere ?")

Hello all,

some llvm classes, are so well-known and widely used, that qualifying 
them with "llvm::" serves no useful purpose and only adds visual noise. 
I'm thinking here mainly of ADT classes like String/ArrayRef, 
Optional/Error, etc. I propose we stop explicitly qualifying these classes.

We can implement this proposal the same way as clang solved the same 
problem, which is by creating a special LLVM.h 
header in the Utility library. This header would adopt these classes 
into the lldb_private namespace via a series of forward and "using" 

I think clang's LLVM.h is contains a well-balanced collection of adopted 
classes, and it should cover the most widely-used classes in lldb too, 
so I propose we use that as a starting point.

What do you think?


PS: I'm not proposing any wholesale removal of "llvm::" qualifiers from 
these types, though I may do some smaller-scale removals if I'm about to 
substantially modify a file.
