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.

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.

This reverts commit 342d92c7a0adeabc9ab00f3f0d88d739fe7da4c7.
Turns out we're going with a different schema design to represent
DW_TAG_imported_modules so we won't need this extra field.

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.

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.

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.

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.

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.

to finalize MI bundles (i.e. add BUNDLE instruction and computing register def
and use lists of the BUNDLE instruction) and a pass to unpack bundles.
- Teach more of MachineBasic and MachineInstr methods to be bundle aware.
- Switch Thumb2 IT block to MI bundles and delete the hazard recognizer hack to
prevent IT blocks from being broken apart.
