This commit moves `MDLocation`, finishing off PR21433. There's an
accompanying clang commit for frontend testcases. I'll attach the
testcase upgrade script I used to PR21433 to help out-of-tree
frontends/backends.
This changes the schema for `DebugLoc` and `DILocation` from:
!{i32 3, i32 7, !7, !8}
to:
!MDLocation(line: 3, column: 7, scope: !7, inlinedAt: !8)
Note that empty fields (line/column: 0 and inlinedAt: null) don't get
printed by the assembly writer.

; FIXME: A potentially more interesting test case would be:

|
; %call = @bar()
|
|
; dbg.value j=0
|
|
; %call2 = @bar()
|
|
; dbg.value j=%call
|
|
;
|
|
; We cannot current handle the above sequence because codegenprepare
|
|
; hoists the second dbg.value above %call2, which then appears to
|
|
; conflict with j=0. It does this because SelectionDAG cannot handle
|
|
; global debug values.
