[GlobalISel] Handle multiple registers in dbg.value intrinsic https://reviews.llvm.org/D66077 The value passed into dbg.value may relate to multiple registers, each of which need a DBG_VALUE. This fix calls MIRBuilder.buildDirectDbgValue for each register. Without this, IR passed in from flang-compiler/flang may fail an assertion in getOrCreateVReg.

[lit][REQUIRES] Fix some tests with incorrect REQUIRES clauses These weren't running anywhere because of bad specifications. One test has bit-rotted and had to be XFAILed, the rest are okay. Differential Revision: https://reviews.llvm.org/D136612

[DebugMetadata][DwarfDebug] Fix DWARF emisson of function-local imported entities (3/7) RFC https://discourse.llvm.org/t/rfc-dwarfdebug-fix-and-improve-handling-imported-entities-types-and-static-local-in-subprogram-and-lexical-block-scopes/68544 Fixed PR51501 (tests from D112337). 1. Reuse of DISubprogram's 'retainedNodes' to track other function-local entities together with local variables and labels (this patch cares about function-local import while D144006 and D144008 use the same approach for local types and static variables). So, effectively this patch moves ownership of tracking local import from DICompileUnit's 'imports' field to DISubprogram's 'retainedNodes' and adjusts DWARF emitter for the new layout. The old layout is considered unsupported (DwarfDebug would assert on such debug metadata). DICompileUnit's 'imports' field is supposed to track global imported declarations as it does before. This addresses various FIXMEs and simplifies the next part of the patch. 2. Postpone emission of function-local imported entities from `DwarfDebug::endFunctionImpl()` to `DwarfDebug::endModule()`. While in `DwarfDebug::endFunctionImpl()` we do not have all the information about a parent subprogram or a referring subprogram (whether a subprogram inlined or not), so we can't guarantee we emit an imported entity correctly and place it in a proper subprogram tree. So now, we just gather needed details about the import itself and its parent entity (either a Subprogram or a LexicalBlock) during processing in `DwarfDebug::endFunctionImpl()`, but all the real work is done in `DwarfDebug::endModule()` when we have all the required information to make proper emission.
