Generalize printing of nested-name-specifier sequences for use in both
QualifiedNameType and QualifiedDeclRefExpr. We now keep track of the

Extend the use of QualifiedNameType to the creation of class template

Introduce a representation for types that we referred to via a
qualified name, e.g.,

  foo::x

so that we retain the nested-name-specifier as written in the source
code and can reproduce that qualified name when printing the types
back (e.g., in diagnostics). This is PR3493, which won't be complete
until finished the other tasks mentioned near the end of this commit.

The parser's representation of nested-name-specifiers, CXXScopeSpec,
is now a bit fatter, because it needs to contain the scopes that
precede each '::' and keep track of whether the global scoping
operator '::' was at the beginning. For example, we need to keep track
of the leading '::', 'foo', and 'bar' in

  ::foo::bar::x

The Action's CXXScopeTy * is no longer a DeclContext *. It's now the
opaque version of the new NestedNameSpecifier, which contains a single
component of a nested-name-specifier (either a DeclContext * or a Type
*, bitmangled).

The new sugar type QualifiedNameType composes a sequence of
NestedNameSpecifiers with a representation of the type we're actually
referring to. At present, we only build QualifiedNameType nodes within
Sema::getTypeName. This will be extended to other type-constructing
actions (e.g., ActOnClassTemplateId).

Also on the way: QualifiedDeclRefExprs will also store a sequence of
NestedNameSpecifiers, so that we can print out the property
nested-name-specifier. I expect to also use this for handling
dependent names like Fibonacci<I - 1>::value.

Driver: Rename Command::Argv to Command::Arguments to make it clearer
that this does not include the implicit first argument (the executable
name).

Driver: Don't claim inputs when pipelining, a tool should eventually
claim these.

Fix -E mismatch; an identifier followed by a numeric constant does not
require a space (to avoid concatenation) if the numeric constant had a
leading period.
 - PR3819.

Driver: Ditch Driver::DefaultToolChain, this can vary between compilations.

Driver: I was too hasty in free'ing Actions, we sometimes share
Actions so a simple tree traversal isn't quite good enough. Leaving a
FIXME for now.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67161 91177308-0d34-0410-b5e6-96231b3b80d8

Driver: Move actions into Compilation, and construct the compilation
earlier.

 - This gives us a simple ownership model, and allows clients access
   to more information should they ever want it.

 - We now free Actions correctly.

Driver: Add test for binding of precompile; exposed bug due to my
flawed idea that llvm::sys::Path::getBasename was a version of
basename().
