Add a subclass of `MDScope` to explicitly categorize the legal scopes for locals -- in particular, scopes that are legal for `MDLocation`, `MDLexicalBlockBase`, and `MDLocalVariable`. This provides a convenient `isa<>` target for the verifier, and eventually I'll be changing the above classes' `getScope()` to specifically return it. Currently, its subclasses are `MDSubprogram`, `MDLexicalBlock`, and `MDLexicalBlockFile`. I've gone with `MDLocalScope` for now -- a little ambiguous since it's a scope *for* locals, not a scope that's local -- but I'm open to more descriptive names if someone can think of something better. Regardless, the code docs should make it clear enough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233092 91177308-0d34-0410-b5e6-96231b3b80d8
