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.

d854299712 Remove the ARM-specific variant of this test. It's already covered by
the ARM build bots, and it adds a weird case to the test suite where
a test uses as inputs files in the parent directory.

Talked about this with Dave on IRC and he's fine with this approach even
though it isn't optimal.

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.

14891447ff Update debug info test cases with empty SplitDebugFilename field.
This could be 'null' or the empty string, DIDescriptor::getStringField
coalesces the two cases anyway so it's just a matter of legible/efficient
representation.

The change in behavior of the DICompileUnit::get* functions could be
subsumed by the full verification check - but ideally that should just be an
assertion if we could front-load the actual debug info metadata failure paths.

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.

3de61b4c01 Debug Info: store the files and directories for each compile unit.
We now emit a line table for each compile unit. To reduce the prologue size
of each line table, the files and directories used by each compile unit are
stored in std::map<unsigned, std::vector< > > instead of std::vector< >.

The prologue for a lto'ed image can be as big as 93K. Duplicating 93K for each
compile unit causes a huge increase of debug info. With this patch, each
prologue will only emit the files required by the compile unit.

7bf3d6a043 Previously, parsing capability of the .debug_frame section was added
to lib/DebugInfo, with dumping in llvm-dwarfdump. This patch adds
initial ability to parse and dump CFA instructions contained in
entries.

To keep it manageable, the patch omits some more advanced capabilities
(accounted in TODOs):

* Parsing of instructions with BLOCK arguments (expression lists)
* Dumping of actual instruction arguments (currently only names are
dumped). This is quite tricky since the dumper has to effectively
"interpret" the instructions.
