Only around 50% of the intrinsics in this file are documented now. The patches for the rest of the intrisics in this file will be send out later.
The doxygen comments are automatically generated based on Sony's intrinsics docu
ment.
I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream. This patch was internally reviewed by Paul Robinson.

decomposition declarations.
There are a couple of things in the wording that seem strange here:
decomposition declarations are permitted at namespace scope (which we partially
support here) and they are permitted as the declaration in a template (which we
reject).

Processing update records (and loading a module, in general) might trigger
unexpected calls to the ASTWriter (being a mutation listener). Now we have a
mechanism to suppress those calls to the ASTWriter but notify other possible
mutation listeners.

Summary:
This patch enables .rgba accessors to ext_vector_type types and adds
tests for syntax validation and code generation.
'a' and 'b' can appear either in the point access mode or the numeric
access mode (for indices 10 and 11). To disambiguate between the two
usages, the accessor type is explicitly passed to relevant methods.

This change depends on the corresponding LLVM change at:
https://reviews.llvm.org/D22519
The llvm.invariant.start and llvm.invariant.end intrinsics currently
support specifying invariant memory objects only in the default address
space.
With this LLVM change, these intrinsics are overloaded for any adddress space
for memory objects and we can use these llvm invariant intrinsics in
non-default address spaces.
Example: llvm.invariant.start.p1i8(i64 4, i8 addrspace(1)* %ptr)
This overloaded intrinsic is needed for representing final or invariant
memory in managed languages.

As discussed on D22460, I've updated the vbroadcastf128 pd256/ps256 builtins to map directly to generic IR - load+splat a 128-bit vector to both lanes of a 256-bit vector.
Fix for PR28657.

The builder prints out the following IR:
\5CCoverageMapping\5COutput\5Ctest\5Cf1.c
The updated test in r276367 expects path separators to be either '/' or
'\\', so it chokes on the unexpected "5C" stuff. I'm not sure what that
is, but I included a kludge that should work around it.

We should be able to use `mkdir` without turning on `REQUIRES: shell`.
Moreover, this test should check for a path separator which precedes the
relative filename to make sure that absolute paths are being used.

This checker checks copy and move assignment operators whether they are
protected against self-assignment. Since C++ core guidelines discourages
explicit checking for `&rhs==this` in general we take a different approach: in
top-frame analysis we branch the exploded graph for two cases, where &rhs==this
and &rhs!=this and let existing checkers (e.g. unix.Malloc) do the rest of the
work. It is important that we check all copy and move assignment operator in top
frame even if we checked them already since self-assignments may happen
undetected even in the same translation unit (e.g. using random indices for an
array what may or may not be the same).
This reapplies r275820 after fixing a string-lifetime issue discovered by the
bots.

Unreferenced nested structs and classes were omitted from the debug info. In DWARF, this was intentional, to avoid bloat. But for CodeView, we want this information to be consistent with what Microsoft tools would produce and expect.

This can happen when emitting a local decl, which triggers
loading a decl imported from an AST file, which we then
hand to the AST consumer. Timer is not allowed to recurse
so an assertion fire. Keep a reference counter to avoid this
problem. LGTM'd by Richard Smith on IRC.

In atomic builtins, we assumed that the LValue conversion on the first
argument would succeed. So, we would crash given code like:
```
void ovl(char);
void ovl(int);
__atomic_store_n(ovl, 0, 0);
```
This patch makes us not assume that said conversion is successful. :)

OpenMP 4.5 removed the restriction that array section lower bound must be non negative.
This change is to allow negative values for array section based on pointers.
For array section based on array type there is still a restriction: "The array section must be a subset of the original array."

we first touch any part of that module. Instead, defer them until the first
time that module is (transitively) imported. The initializer step for a module
then recursively initializes modules that its own headers imported.
For example, this avoids running the <iostream> global initializer in programs
that don't actually use iostreams, but do use other parts of the standard
library.

'ReusingBase' was a terrible name. It might actually refer to the most
derived class, which is not a base. 'BaseWithVPtr' was also bad, since
again, it could refer to the most derived class. It was actually the
first base to introduce the vptr, so now it is 'IntroducingObject'.

D20859 and D20860 attempted to replace the SSE (V)CVTTPS2DQ and VCVTTPD2DQ truncating conversions with generic IR instead.
It turns out that the behaviour of these intrinsics is different enough from generic IR that this will cause problems, INF/NAN/out of range values are guaranteed to result in a 0x80000000 value - which plays havoc with constant folding which converts them to either zero or UNDEF. This is also an issue with the scalar implementations (which were already generic IR and what I was trying to match).
This patch changes both scalar and packed versions back to using x86-specific builtins.
It also deals with the other scalar conversion cases that are runtime rounding mode dependent and can have similar issues with constant folding.

Summary:
Space for storing the //constraint-expression// of the
//requires-clause// associated with a `TemplateParameterList` is
arranged by taking a bit out of the `NumParams` field for the purpose
of determining whether there is a //requires-clause// or not, and by
adding to the trailing objects tied to the `TemplateParameterList`. An
accessor is provided.
An appropriate argument is supplied to `TemplateParameterList::Create`
at the various call sites.
Serialization changes will addressed as the Concepts implementation
becomes more solid.
Drive-by fix:
This change also replaces the custom
`FixedSizeTemplateParameterListStorage` implementation with one that
follows the interface provided by `llvm::TrailingObjects`.

Sema actions on ObjCDictionaryLiteral and ObjCArryLiteral are currently
done as a side-effect of Sema upon parent expressions, which incurs of
delayed typo corrections for such literals to be performed by TypoTransforms
upon the ObjCDictionaryLiteral and ObjCArryLiteral themselves instead of
its elements individually.
This is specially bad because it was not designed to act on several
elements; searching through all possible combinations of corrections for
several elements is very expensive. Additionally, when one of the
elements has no correction candidate, we still explore all options and
at the end emit no typo corrections whatsoever.
Do the proper sema actions by acting on each element alone during appropriate
literal parsing time to get proper diagonistics and decent compile time
behavior.
