c462db6d66 Revert "Revert "PR14606: debug info imported_module support""
This reverts commit r179840 with a fix to test/DebugInfo/two-cus-from-same-file.ll

I'm not sure why that test only failed on ARM & MIPS and not X86 Linux, even
though the debug info was clearly invalid on all of them, but this ought to fix
it.

This reverts commit r179836 as it seems to have caused test failures.

bcb81360a2 PR14606: debug info imported_module support
Adding another CU-wide list, in this case of imported_modules (since they
should be relatively rare, it seemed better to add a list where each element
had a "context" value, rather than add a (usually empty) list to every scope).
This takes care of DW_TAG_imported_module, but to fully address PR14606 we'll
need to expand this to cover DW_TAG_imported_declaration too.

72dfb052ab Revert "Adding DIImportedModules to DIScopes."
This reverts commit 342d92c7a0.

Turns out we're going with a different schema design to represent
DW_TAG_imported_modules so we won't need this extra field.

342d92c7a0 Adding DIImportedModules to DIScopes.
This is just the basic groundwork for supporting DW_TAG_imported_module but I
wanted to commit this before pushing support further into Clang or LLVM so that
this rather churny change is isolated from the rest of the work. The major
churn here is obviously adding another field (within the common DIScope prefix)
to all DIScopes (files, classes, namespaces, lexical scopes, etc). This should
be the last big churny change needed for DW_TAG_imported_module/using directive
support/PR14606.

b4cf0ab22b Split out filename & directory from DIFile to start generalizing over DIScopes
This is the first step to making all DIScopes have a common metadata prefix (so
that things (using directives, for example) that can appear in any scope can be
added to that common prefix). DIFile is itself a DIScope so the common prefix
of all DIScopes cannot be a DIFile - instead it's the raw filename/directory
name pair.

de3077ae6b Refactor filename/directory in DICompileUnit into a DIFile
This is the next step towards making the metadata for DIScopes have a common
prefix rather than having to delegate based on their tag type.

850b74d392 Upgrading debug info test cases to be (more) compatible with the current debug info format.
These cases were found by further work to remove support for debug info
versioning. Common cleanups (other than changing the version info in the tag
field) included adding the last parameter to compile_units (recently added for
fission support) and other cases of trailing fields in lexical blocks, compile
units, and subprograms.

d7e0de5956 Upgrade tests to the latest debug info format.
Mostly this is just changing the named metadata (llvm.dbg.sp, llvm.dbg.gv,
llvm.dbg.<func>.lv, etc -> llvm.dbg.cu), adding a few fields to older records
(DIVariable: flags/inlined-at, DICompileUnit: sp/gv/types,
DISubprogram: local variables list)

The tests to update were discovered by a change I'm working on to remove debug
info version support - so any tests using old debug info versions I haven't
updated probably are bad tests or just not actually designed to test debug
info.

547be2699c Don't print a label before .cfi_startproc when we don't need to. This makes
the produce assembly when using CFI just a bit more readable.

93d39be530 Do not use named md nodes to track variables that are completely optimized. This does not scale while doing LTO with debug info. New approach is to include list of variables in the subprogram info directly.

c722c3d5ff While extending definition range of a debug variable, consult lexical scopes also. There is no point extending debug variable out side its lexical block. This provides 6x compile time speedup in some cases.
