These date back to when the non-intrinsic format of variable locations was still being tested and was behind a compile-time flag, so not all builds / bots would correctly run them. The solution at the time, to get at least some test coverage, was to have tests opt-in to non-intrinsic debug-info if it was built into LLVM. Nowadays, non-intrinsic format is the default and has been on for more than a year, there's no need for this flag to exist. (I've downgraded the flag from "try" to explicitly requesting non-intrinsic format in some places, so that we can deal with tests that are explicitly about non-intrinsic format in their own commit).
The change is fairly mechanical: 1. Factor code from `FastISel::selectIntrinsicCall`, which converts debug intrinsics into debug instructions, into functions (NFC). 2. Call those functions for DPValues attached to instructions too. The test updates look the same as other RemoveDIs changes: re-run the tests with `--try-experimental-debuginfo-iterators`, which checks the output is identical using the new debug info format (if it has been enabled in the cmake configuration). Depends on #76941 (otherwise some modified tests spuriously fail).

This patch removes the verbose option from tests that do not need it and simplifies the checks. For tests that do have the verbose option, the checks were standardized to be more readable and consistent. Reviewed By: shchenz, dblaikie Differential Revision: https://reviews.llvm.org/D112636

Summary: The lit feature object-emission was added because Hexagon did not support the integrated assembler, so some tests needed to be turned off with a Hexagon target. Hexagon now supports the integrated assembler, so this feature can be removed.

In order to set breakpoints on labels and list source code around labels, we need collect debug information for labels, i.e., label name, the function label belong, line number in the file, and the address label located. In order to keep these information in LLVM IR and to allow backend to generate debug information correctly. We create a new kind of metadata for labels, DILabel. The format of DILabel is !DILabel(scope: !1, name: "foo", file: !2, line: 3) We hope to keep debug information as much as possible even the code is optimized. So, we create a new kind of intrinsic for label metadata to avoid the metadata is eliminated with basic block. The intrinsic will keep existing if we keep it from optimized out. The format of the intrinsic is llvm.dbg.label(metadata !1) It has only one argument, that is the DILabel metadata. The intrinsic will follow the label immediately. Backend could get the label metadata through the intrinsic's parameter. We also create DIBuilder API for labels to be used by Frontend. Frontend could use createLabel() to allocate DILabel objects, and use insertLabel() to insert llvm.dbg.label intrinsic in LLVM IR.
