This also broke the build for MSVC when doing a debug build (though no
builder seems to be picking up the failure!). After working around a
handful of link errors, I came to one that's going to require more
understanding of LLVM's tablegen than I have.

Error LNK2019 unresolved external symbol "public: void __cdecl
`anonymous namespace'::MatchableInfo::dump(void)const "
(?dump at MatchableInfo@?A0xf4f1c304@@QEBAXXZ) referenced in function
"public: void __cdecl `anonymous
namespace'::AsmMatcherEmitter::run(class llvm::raw_ostream &)"
(?run at AsmMatcherEmitter@?A0xf4f1c304@@QEAAXAEAVraw_ostream at llvm@@@Z)
llvm-tblgen D:\llvm\2017\utils\TableGen\AsmMatcherEmitter.obj 1

Since this has been broken for over a day and the fixes are
nontrivial, I've reverted your commit (r315590) in r315854. Hopefully
this doesn't cause you too many problems!
