Add LLVMContext, which will eventually be used as a container for privatizing a lot of (currently) global state, including the
constant and type uniquing tables. For now, just make it a wrapper around the existing APIs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74488 91177308-0d34-0410-b5e6-96231b3b80d8
