Dimitry Andric 59e5cb4342 Fix compile with GCC 5 or later
Summary:

Compiling with GCC 5 or later can fail with a bogus error "constructor
required before non-static data member for
llvm::ValueEnumerator::MDRange::First has been parsed".

This was originally fixed upstream in GCC PR 70528, but later this fix
was reverted, and released versions of GCC still show the bogus error.

To work around this, replace MDRange's declaration of a default
constructor with a definition.
