This reverts commit r224451. It caused us to reject some valid existing
code.
This code appears to run in non-error cases as well as error cases. If
the scope of a DependentScopeDeclRefExpr is still incomplete it probably
means we still have more instantiation to do.

A DependentScopeDeclRefExpr should always have a nested name specifier.
During template instantiation, if we found that the named context was
incomplete, we would previously build a DependentScopeDeclRefExpr with
an empty qualifier.
This error recovery path has been asserting for some time. The other
error codepaths use ExprError, so we can do the same.
Fixes PR21864.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

I'm not completely sure this is the right way to fix this issue, but it seems
reasonable, and it's consistent with the non-template code for this
construct.
