IR: Allow MDSubrange to have 'count: -1' It turns out that `count: -1` is a special value indicating an empty array, such as `Values` in: struct T { unsigned Count; int Values[]; }; Handle it. llvm-svn: 229769

[DebugInfo] Upgrade DISubrange to support Fortran dynamic arrays This patch upgrades DISubrange to support fortran requirements. Summary: Below are the updates/addition of fields. lowerBound - Now accepts signed integer or DIVariable or DIExpression, earlier it accepted only signed integer. upperBound - This field is now added and accepts signed interger or DIVariable or DIExpression. stride - This field is now added and accepts signed interger or DIVariable or DIExpression. This is required to describe bounds of array which are known at runtime. Testing: unit test cases added (hand-written) check clang check llvm check debug-info Reviewed By: aprantl Differential Revision: https://reviews.llvm.org/D80197

IR: Give 'DI' prefix to debug info metadata 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. llvm-svn: 236120
