Summary:
We introduce a strict policy for C++ CTU. It can work across TUs only if
the C++ dialects are the same. We neither allow C vs C++ CTU. We do this
because the same constructs might be represented with different properties in
the corresponding AST nodes or even the nodes might be completely different (a
struct will be RecordDecl in C, but it will be a CXXRectordDecl in C++, thus it
may cause certain assertions during cast operations).

Summary:
Adding some more CTU list tests. E.g. to check if a construct is unsupported.
We also slightly modify the handling of the return value of the `Import`
function from ASTImporter.

Inline cpu_specific versions referenced before the cpu_dispatch function
weren't properly emitted, since they hadn't been referred to. This
patch ensures that during resolver generation that all appropriate
versions are emitted.

Summary:
With a new switch we may be able to print to stderr if a new TU is being loaded
during CTU. This is very important for higher level scripts (like CodeChecker)
to be able to parse this output so they can create e.g. a zip file in case of
a Clang crash which contains all the related TU files.

Summary:
...that fires when running completion inside an argument of
UnresolvedMemberExpr (see the added test).
The assertion that fires is from Sema::TryObjectArgumentInitialization:
assert(FromClassification.isLValue());
This happens because Sema::AddFunctionCandidates does not account for
object types which are pointers. It ends up classifying them incorrectly.
All usages of the function outside code completion are used to run
overload resolution for operators. In those cases the object type being
passed is always a non-pointer type, so it's not surprising the function
did not expect a pointer in the object argument.
However, code completion reuses the same function and calls it with the
object argument coming from UnresolvedMemberExpr, which can be a pointer
if the member expr is an arrow ('->') access.
Extending AddFunctionCandidates to allow pointer object types does not
seem too crazy since all the functions down the call chain can properly
handle pointer object types if we properly classify the object argument
as an l-value, i.e. the classification of the implicitly dereferenced
pointer.

Summary:
We plan to introduce additional CTU related lit test. Since lit may run the
tests in parallel, it is not safe to use the same directory (%T) for these
tests. It is safe to use however test case specific directories (%t).

Thunks that return member pointers via sret are broken due to using temporary
storage for the return value on the stack and then passing that pointer to a
tail call, violating the rule that a tail call can't access allocas in the
caller (see bug).
Since r90526, we put aggregate return values directly in the sret slot, but
this doesn't apply to member pointers which are considered scalar.
Unless I'm missing something subtle, we should be able to always use the sret
slot directly for indirect return values.

The flag -fdebug-compilation-dir is useful to make generated .o files
independent of the path of the build directory, without making the compile
command-line dependent on the path of the build directory, like
-fdebug-prefix-map requires. This change makes it so that the driver can
forward the flag to -cc1as, like it already can for -cc1. We might want to
consider making -fdebug-compilation-dir a driver flag in a follow-up.
(Since -fdebug-compilation-dir defaults to PWD, it's already possible to get
this effect by setting PWD, but explicit compiler flags are better than env
vars, because e.g. ninja tracks command lines and reruns commands that change.)
Somewhat related to PR14625.

This reverts commit r348280 and reapplies D55085 without modifications.
Original commit message:
Avoid emitting redundant or unusable directories in DIFile metadata entries.
As discussed on llvm-dev recently, Clang currently emits redundant
directories in DIFile entries, such as
.file 1 "/Volumes/Data/llvm" "/Volumes/Data/llvm/tools/clang/test/CodeGen/debug-info-abspath.c"
This patch looks at any common prefix between the compilation
directory and the (absolute) file path and strips the redundant
part. More importantly it leaves the compilation directory empty if
the two paths have no common prefix.
After this patch the above entry is (assuming a compilation dir of "/Volumes/Data/llvm/_build"):
.file 1 "/Volumes/Data/llvm" "tools/clang/test/CodeGen/debug-info-abspath.c"
When building the FileCheck binary with debug info, this patch makes
the build artifacts ~1kb smaller.

If the array section is based on pointer and this sections is mapped in
target region + then it is used in the inner parallel region, it also
must be globalized as the pointer itself is passed by value, not by

Friend function template defined in a class template becomes available if
the enclosing class template is instantiated. Until the function template
is used, it does not have a body, but still is considered a definition for
the purpose of redeclaration checks.
This change modifies redefinition check so that it can find the friend
function template definitions in instantiated classes.

Support the Swift calling convention on Windows ARM and AArch64. Both
of these conform to the AAPCS, AAPCS64 calling convention, and LLVM has
been adjusted to account for the register usage. Ensure that the
