Finish off PR23080 by renaming the debug info IR constructs from `MD*` to `DI*`. The last of the `DIDescriptor` classes were deleted in r235356, and the last of the related typedefs removed in r235413, so this has all baked for about a week. Note: If you have out-of-tree code (like a frontend), I recommend that you get everything compiling and tests passing with the *previous* commit before updating to this one. It'll be easier to keep track of what code is using the `DIDescriptor` hierarchy and what you've already updated, and I think you're extremely unlikely to insert bugs. YMMV of course. Back to *this* commit: I did this using the rename-md-di-nodes.sh upgrade script I've attached to PR23080 (both code and testcases) and filtered through clang-format-diff.py. I edited the tests for test/Assembler/invalid-generic-debug-node-*.ll by hand since the columns were off-by-three. It should work on your out-of-tree testcases (and code, if you've followed the advice in the previous paragraph). Some of the tests are in badly named files now (e.g., test/Assembler/invalid-mdcompositetype-missing-tag.ll should be 'dicompositetype'); I'll come back and move the files in a follow-up commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236120 91177308-0d34-0410-b5e6-96231b3b80d8

; This testcase tests the following flow:
|
|
; - File A defines a linkonce_odr version of @foo which has inlined into @bar.
|
|
; - File B defines a weak_odr version of @foo (identical definition).
|
|
; - Linkage rules state File B version of @foo wins.
|
|
; - Debug info for the subprograms of @foo match exactly. Without
|
|
; intervention, the same subprogram would show up in both compile units, and
|
|
; it would get associated with the compile unit where it was linkonce.
|
|
; - @bar has inlined debug info related to the linkonce_odr @foo.
