The primary goal here is to make the type node hierarchy available to
other tblgen backends, although it should also make it easier to generate
more selective x-macros in the future.
Because tblgen doesn't seem to allow backends to preserve the source
order of defs, this is not NFC because it significantly re-orders IDs.
I've fixed the one (fortunately obvious) place where we relied on
the old order. Unfortunately, I wasn't able to share code with the
existing AST-node x-macro generators because the x-macro schema we use
for types is different in a number of ways. The main loss is that
subclasses aren't ordered together, which doesn't seem important for
types because the hierarchy is generally very shallow with little
clustering.

Allow setting a MinVersion, stating from which OpenCL version a
builtin function is available, and a MaxVersion, stating from which
OpenCL version a builtin function should not be available anymore.
Guard some definitions of the "work-item" builtin functions according
to the OpenCL versions from which they are available.
Add the "vector data load and store" builtin functions (e.g.
vload/vstore), whose signatures differ before and after OpenCL 2.0 in
the pointer argument address spaces.

In order to enable future improvements to our attribute diagnostics,
this moves info from ParsedAttr into CommonAttributeInfo, then makes
this type the base of the *Attr and ParsedAttr types. Quite a bit of

Rename the image type definitions in the .td file to make them

Generic types are an abstraction of type sets. It mimics the way
functions are defined in the OpenCL specification. For example,
floatN can abstract all the vector sizes of the float type.
This allows to
* stick more closely to the specification, which uses generic types;
* factorize definitions of functions with numerous prototypes in the
tablegen file; and
* reduce the memory impact of functions with many overloads.

When -trim-egraph is unavailable (say, when you're debugging a crash on
a real-world code that takes too long to reduce), it makes sense to view
the untrimmed graph up to the crashing node's predecessor, then dump the ID
(or a pointer) of the node in the attached debugger, and then trim
the dumped graph in order to keep only paths from the root to the node.
The newly added --to flag does exactly that:
$ exploded-graph-rewriter.py ExprEngine.dot --to 0x12229acd0
Multiple nodes can be specified. Stable IDs of nodes can be used
instead of pointers.

Explorers aren't the right abstraction. For the purposes of displaying svg files
we don't care in which order do we explore the nodes. We may care about this for
other analyses, but we're not there yet.
The function of cutting out chunks of the graph is performed poorly by
the explorers, because querying predecessors/successors on the explored nodes
yields original successors/predecessors even if they aren't being explored.
Introduce a new entity, "trimmers", that do one thing but to it right: cut out
chunks of the graph. Trimmers mutate the graph, so stale edges aren't even
visible to their consumers in the pipeline. Additionally, trimmers are
intrinsically composable: multiple trimmers can be applied to the graph
sequentially.
Refactor the single-path explorer into the single-path trimmer.
Rename the test file for consistency.

Change the default behavior: the tool no longer dumps the rewritten .dot file
to stdout, but instead it automatically converts it into an .html file
(which essentially wraps an .svg file) and immediately opens it with
the default web browser.
This means that the tool should now be fairly easy to use:
$ exploded-graph-rewriter.py /tmp/ExprEngine.dot
The benefits of wrapping the .svg file into an .html file are:
- It'll open in a web browser, which is the intended behavior.
An .svg file would be open with an image viewer/editor instead.
- It avoids the white background around the otherwise dark svg area
in dark mode.
The feature can be turned off by passing a flag '--rewrite-only'.
The LIT substitution is updated to enforce the old mode because
we don't want web browsers opening on our buildbots.

A few minor refinements to other types
llvm-svn: 367199
Summary:
This is the first part of work announced in
"[RFC] Adding lifetime analysis to clang" [0],
i.e. the addition of the [[gsl::Owner(T)]] and
[[gsl::Pointer(T)]] attributes, which
will enable user-defined types to participate in
the lifetime analysis (which will be part of the
next PR).
The type `T` here is called "DerefType" in the paper,
and denotes the type that an Owner owns and a Pointer
points to. E.g. `std::vector<int>` should be annotated
with `[[gsl::Owner(int)]]` and
a `std::vector<int>::iterator` with `[[gsl::Pointer(int)]]`.
