The inline keyword is not defined in the C89 standard, so source files
that include arm_sve.h will fail compilation if -std=c89 is specified.
For consistency with arm_neon.h, we should use __inline__ instead.

This attribute permits a typedef to be associated with a class template
specialization as a preferred way of naming that class template
specialization. This permits us to specify that (for example) the
preferred way to express 'std::basic_string<char>' is as 'std::string'.
The attribute is applied to the various class templates in libc++ that have
corresponding well-known typedef names.
This is a re-commit. The previous commit was reverted because it exposed
a pre-existing bug that has since been fixed / worked around; see

This was motivated by changes to llvm's `not --crash` disabling symbolization
but I ended up removing `not` from the script entirely because it
returns differently depending on whether clang "crashes" or exits for some
other reason. The script had to choose between calling `not` and `not --crash`
and sometimes it was wrong.
The script also now disables symbolization when we don't read the stack
trace because symbolizing is kind of slow.

There are two factory functions used to create a semantic attribute,
Create() and CreateImplicit(). CreateImplicit() does not need to
specify the source range of the attribute since it's an implicitly-
generated attribute. The same logic does not apply to Create(), so
this removes the default argument from those declarations to avoid
accidentally creating a semantic attribute without source location
information.
Similar to the previous patch, this doesn't convert *all* the classes that
could be converted. It also doesn't enforce any new invariants etc.
It *does* include some data we don't use yet: specific token types that are
allowed and optional/required status of sequence items. (Similar to Dmitri's
prototype). I think these are easier to add as we go than later, and serve
a useful documentation purpose.

This defines two node archetypes with trivial class definitions:
- Alternatives: the generated abstract classes are trivial as all
functionality is via LLVM RTTI
- Unconstrained: this is a placeholder, I think all of these are going to be
Lists but today they have no special accessors etc, so we just say
"could contain anything", and migrate them one-by-one to Sequence later.
Compared to Dmitri's prototype, Nodes.td looks more like a class hierarchy and
less like a grammar. (E.g. variants list the Alternatives parent rather than
vice versa).
The main reasons for this:
- the hierarchy is an important part of the API we want direct control over.
- e.g. we may introduce abstract bases like "loop" that the grammar doesn't
care about in order to model is-a concepts that might make refactorings
more expressive. This is less natural in a grammar-like idiom.
- e.g. we're likely to have to model some alternatives as variants and others
as class hierarchies, the choice will probably be based on natural is-a
relationships.
- it reduces the cognitive load of switching from editing *.td to working with
code that uses the generated classes

In CUDA/HIP a function may become implicit host device function by
pragma or constexpr. A host device function is checked in both
host and device compilation. However it may be emitted only
on host or device side, therefore the diagnostics should be
deferred until it is known to be emitted.
Currently clang is only able to defer certain diagnostics. This causes
false alarms and limits the usefulness of host device functions.
This patch lets clang defer all overloading resolution diagnostics for host device functions.
An option -fgpu-defer-diag is added to control this behavior. By default
it is off.
It is NFC for other languages.

Summary:
Whith the number of projects growing, it is important to be able to
filter them in a more convenient way than by names. It is especially
important for benchmarks, when it is not viable to analyze big
projects 20 or 50 times in a row.
Because of this reason, this commit adds a notion of sizes and a
filtering interface that puts a limit on a maximum size of the project
to analyze or benchmark.
Sizes assigned to the projects in this commit, do not directly
correspond to the number of lines or files in the project. The key
factor that is important for the developers of the analyzer is the
time it takes to analyze the project. And for this very reason,
"size" basically helps to cluster projects based on their analysis
time.

The only modification to the paper was to correct the date for the deprecated
attribute to be 201904L (the corrected date value will be present in WG14
N2553 when it gets published).
Before the patch `SATest compare`, produced quite obscure results
when something about the diagnostic have changed (i.e. its description
or the name of the corresponding checker) because it was simply two
lists of warnings, ADDED and REMOVED. It was up to the developer
to match those warnings, understand that they are essentially the
same, and figure out what caused the difference.
This patch introduces another category of results: MODIFIED.
It tries to match new warnings against the old ones and prints out
clues on what is different between two builds.

ClangAttrEmitter.cpp generates ParsedAttr derived classes with virtual overrides in them (which end up in AttrParsedAttrImpl.inc); this patch ensures these generated functions are marked override, and not (redundantly) virtual.
