Duncan P. N. Exon Smith 1ef70ff39b IR: Make metadata typeless in assembly
Now that `Metadata` is typeless, reflect that in the assembly.  These
are the matching assembly changes for the metadata/value split in
r223802.

  - Only use the `metadata` type when referencing metadata from a call
    intrinsic -- i.e., only when it's used as a `Value`.

  - Stop pretending that `ValueAsMetadata` is wrapped in an `MDNode`
    when referencing it from call intrinsics.

So, assembly like this:

    define @foo(i32 %v) {
      call void @llvm.foo(metadata !{i32 %v}, metadata )
      call void @llvm.foo(metadata !{i32 7}, metadata )
      call void @llvm.foo(metadata , metadata )
      call void @llvm.foo(metadata , metadata )
      call void @llvm.foo(metadata !{metadata !3}, metadata )
      ret void, !bar 
    }
     = metadata !{metadata !2}
     = metadata !{i32* @global}
     = metadata !{metadata !3}
     = metadata !{}

turns into this:

    define @foo(i32 %v) {
      call void @llvm.foo(metadata i32 %v, metadata )
      call void @llvm.foo(metadata i32 7, metadata )
      call void @llvm.foo(metadata i32* @global, metadata )
      call void @llvm.foo(metadata , metadata )
      call void @llvm.foo(metadata !{!3}, metadata )
      ret void, !bar 
    }
     = !{!2}
     = !{i32* @global}
     = !{!3}
     = !{}

I wrote an upgrade script that handled almost all of the tests in llvm
and many of the tests in cfe (even handling many `CHECK` lines).  I've
attached it (or will attach it in a moment if you're speedy) to PR21532
to help everyone update their out-of-tree testcases.

This is part of PR21532.
