-target has no OS version
This ensures that Clang won't warn about redundant -m<os>-version-min
argument for an invocation like
`-target x86_64-apple-macos -mmacos-version-min=10.11`

I based that commit on what was in Intel's public documentation here https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming-reference.pdf
Which specifically said CLWB wasn't until Icelake.
But I've since cross checked with SDE and it thinks these features exist on CNL and ICL. So now I don't know what to believe.
I've added test coverage of the current behavior as part of the revert so at least now have proof of what we're doing.

Summary:
Previsouly clang tried instantiating member initializers even if ctor
body was skipped, this caused spurious errors (see the test).

Suggest moving the following erroneous attrib list (based on location)
[[]] struct X;
to
struct [[]] X;
Additionally, added a fixme for the current implementation that diagnoses misplaced attributes to consider using the newly introduced diagnostic (that I think is more user-friendly).

Summary:
This is currently 16 bytes, the patch reduces it to 4.
(Building with clang on linux x84, I guess others are similar)
The only subfield that might need a bigger type is SymbolPropertySet,
I've moved it to the end of the struct so if it grows, SymbolInfo will
only be 8 bytes.
With a full index of namespace-scope symbols from the LLVM project (200k)
loaded into clangd, this saves ~2MB of RAM.

Now tests for metadata created by clang involve compiling code snippets
placed into c/c++ source files and matching interesting patterns in the
obtained textual representation of IR. Writting such tests is a painful
process as metadata often form complex tree-like structures but textual
representation of IR contains only a pile of metadata at the module end.
This change implements IR matchers that may be used to match required
patterns in the binary IR representation. In this case the metadata
structure is not broken and creation of match patterns is easier.
The change adds unit tests for TBAA metadata generation.

Now that in the new TBAA format we allow access types to be of
any object types, including aggregate ones, it becomes critical
to specify types of all sub-objects such aggregates comprise as
their members. In order to meet this requirement, this patch
enables generation of field descriptors for members of array
types.
Differential Revision: https://reviews.llvm.org/D41399
llvm-svn: 321352
Now that the MDBuilder helpers generating TBAA type and access
descriptors in the new format are in place, we can teach clang to
use them when requested.

In case `@import Foo.Private` fails because the submodule doesn't exist,
look for `Foo_Private` (if available) and build/load that module
instead. In that process emit a warning and tell the user about the
assumption.
The intention here is to assist all existing private modules owners
(in ObjC and Swift) to migrate to the new `Foo_Private` syntax.

The standard correctly forbids various decl-specifiers that dont make sense on non-type template parameters - such as the extern in:
template<extern int> struct X;
This patch implements those restrictions (in a fashion similar to the corresponding checks on function parameters within ActOnParamDeclarator).
Credit goes to miyuki (Mikhail Maltsev) for drawing attention to this issue, authoring the initial versions of this patch, and supporting the effort to re-engineer it slightly. Thank you!

We used to advertise private modules to be declared as submodules
(Foo.Private). This has proven to not scale well since private headers
might carry several dependencies, introducing unwanted content into the
main module and often causing dep cycles.
Change the canonical way to name it to Foo_Private, forcing private
modules as top level ones, and provide warnings under -Wprivate-module
to suggest fixes for other private naming. Update documentation to
reflect that.
