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.

; PR14016
|
|
|
|
; Built with clang (then manually running -mem2reg with opt) from the following source:

; void f2() {

; f1(1);

|
|
|
|
; Test both varargs removal and removal of a traditional dead arg together, to
|
|
; test both the basic functionality, and a particular wrinkle involving updating
|
|
; the function->debug info mapping on update to ensure it's accurate when used
|
|
; again for the next removal.
|

|
|
; CHECK: void ()* @_ZL2f1iz, {{.*}} ; [ DW_TAG_subprogram ] {{.*}} [f1]
