OCHyams 0ebf9a8e34 [DebugInfo] Move the findDbg* functions into DebugInfo.cpp
Move the findDbg* functions into lib/IR/DebugInfo.cpp from
lib/Transforms/Utils/Local.cpp.

D99169 adds a call to a function (findDbgUsers) that lives in
lib/Transforms/Utils/Local.cpp (LLVMTransformUtils) from lib/IR/Value.cpp
(LLVMCore). The Core lib doesn't include TransformUtils. The builtbots caught
this here: https://lab.llvm.org/buildbot/#/builders/109/builds/12664. This patch
moves the function, and the 3 similar ones for consistency, into DebugInfo.cpp
which is part of LLVMCore.

Sven van Haastregt 6cb7631df3 [OpenCL] Change OpenCL builtin version encoding
Instead of using a MinVersion and MaxVersion field, encode the version
of a builtin using a mask that aligns better with version handling in
OpenCLOptions.h.  In addition, this saves a field in the BuiltinTable.

This change allows a finer-grained control over the OpenCL versions in
which a builtin is available: instead of a range, we can now toggle
each version individually.

The fine-grained version control is not yet exposed on the TableGen
definitions side, as changes for OpenCL 3 feature optionality still
need to be defined and will affect how we want to expose these.

Evgeniy Brevnov 35e95c6817 [CVP] processCallSite returns wrong status
Recently processMinMaxIntrinsic has been added and we started to observe a number of analysis get invalidated after CVP. The problem is CVP conservatively returns 'true'  even if there were no modifications to IR. I found one more place besides processMinMaxIntrinsic  which has the same problem. I think processMinMaxIntrinsic and similar should better have boolean return status to prevent similar issue reappear in future.

Xun Li fa6b54c44a [Coroutines] Set presplit attribute in Clang instead of CoroEarly pass
Presplit coroutines cannot be inlined. During AlwaysInliner we check if a function is a presplit coroutine, if so we skip inlining.
The presplit coroutine attributes are set in CoroEarly pass.
However in O0 pipeline, AlwaysInliner runs before CoroEarly, so the attribute isn't set yet and will still inline the coroutine.
This causes Clang to crash: https://bugs.llvm.org/show_bug.cgi?id=49920

To fix this, we set the attributes in the Clang front-end instead of in CoroEarly pass.

Revert "[SCEV] Model `ashr exact x, C` as `(abs(x) EXACT/u (1<<C)) * signum(x)`"
As being discussed in https://reviews.llvm.org/D100721,
this modelling is lossy, we can't reconstruct `ash`/`ashr exact`
from it, which means that whenever we actually expand the IR,
we've just pessimized the code..

It would be good to model this pattern, after all it comes up every time
you want to compute a distance between two pointers, but not at this cost.

Stephen Kelly dd68942f1d [AST] Add TypeLoc support to node introspection
Extend the matchers gathering API for types to record template
parameters.  The TypeLoc type hierarchy has some types which are
templates used in CRTP such as PointerLikeTypeLoc.  Record the inherited
template and template arguments of types inheriting those CRTP types in
the ClassInheritance map.  Because the name inherited from is now
computed, the value type in that map changes from StringRef to
std::string.  This also causes the toJSON override signature used to
serialize that map to change.

Remove the logic for skipping over empty ClassData instances.  Several
classes such as TypeOfExprTypeLoc inherit a CRTP class which provides
interesting locations though the derived class does not.  Record it as a
class to make the locations it inherits available.

Record the typeSourceInfo accessors too as they provide access to
TypeLocs in many classes.

The existing unit tests use UnorderedElementsAre to compare the
introspection result with the expected result.  Our current
implementation of google mock (in gmock-generated-matchers.h) is limited
to support for comparing a container of 10 elements.  As we are now
returning more than 10 results for one of the introspection tests,
change it to instead compare against an ordered vector of pairs.

Because a macro is used to generate API strings and API calls, disable
clang-format in blocks of expected results.  Otherwise clang-format
would insert whitespaces which would then be compared against the
introspected strings and fail the test.

Introduce a recursion guard in the generated code.  The TypeLoc class
has IgnoreParens() API which by default returns itself, so it would
otherwise recurse infinitely.

[ADT] Update RPOT to work with specializations of different types.
At the moment, ReversePostOrderTraversal performs a post-order walk on
the entry node of the passed in graph, rather than the graph type
itself.

If GT::NodeRef is the same as GraphT, everything works as expected and
this is the case for the current uses in-tree. But it does not work as
expected if GraphT != GT::NodeRef. In that case, we either fail to build
(if there is no GraphTrait specialization for GT:NodeRef) or we pick the
GraphTrait specialization for GT::NodeRef, instead of the specialization
of GraphT.

Both the depth-first and post-order iterators pick the expected
specalization and this patch updates ReversePostOrderTraversal to
delegate to po_begin & po_end to pick the right specialization, rather
than forcing using GraphTraits<GT::NodeRef>, by first getting the entry
node.

This makes `ReversePostOrderTraversal<Graph<6>> RPOT(G);` build and
work as expected in the test.
