The change preserves the _current_ settings for response-file support.

Differential Revision: https://reviews.llvm.org/D82782
In XCode 12, ld64 got support for @files, in addition to the old
-filelist mechanism. Response files allow passing all command-line
arguments to the linker via a file, rather than just filenames, and is
therefore preferred.
Because of the way response-file support is currently implemented as
part of the Tool class in Clang, this change requires an ugly backdoor
function to access Args. A follow-up commit fixes this, but I've
ordered this change first, for easier backportability.
I've added no tests here, because unfortunately, there don't appear to
be _any_ response-file emission automated tests, and I don't see an
obvious way to add them. I've tested that this change works as
expected locally.

instead of postfix-expressions, and improve error recovery for postfix
operators after unary-expressions.
This covers nullptr, __null, and some calls to type traits with special
parsing rules. We would previously not parse a postfix-expression suffix
for these expressions, so would reject expressions such as
__is_trivial(int)["foo"].
For the case where a postfix-expression suffix is *not* permitted after
a unary-expression (for example, after a new-expression or sizeof
expression), produce a diagnostic if one appears there anyway. That's
always ill-formed, but previously produced very bad diagnostics.
FalsePositiveRefutationBRVisitor had a bug where the constraints were not
properly collected thus crosschecked with Z3.
This patch demonstratest and fixes that bug.
Bug:
The visitor wanted to collect all the constraints on a BugPath.
Since it is a visitor, it stated the visitation of the BugPath with the node
before the ErrorNode. As a final step, it visited the ErrorNode explicitly,
before it processed the collected constraints.
In principle, the ErrorNode should have visited before every other node.
Since the constraints were collected into a map, mapping each symbol to its
RangeSet, if the map already had a mapping with the symbol, then it was skipped.
This behavior was flawed if:
We already had a constraint on a symbol, but at the end in the ErrorNode we have
a tighter constraint on that. Therefore, this visitor would not utilize that
tighter constraint during the crosscheck validation.

When the c preprocessor stringizes tokens, the generated string literals
are affected by the whitespace. This means clang-format can affect
codegen silently, adding spaces and newlines to strings. Practically
speaking, the vast majority of cases will be harmless, only affecting
single identifiers or debug macros.
In the interest of doing no harm in other cases though, this introduces
a blacklist option 'WhitespaceSensitiveMacros', which contains a list of
names of function-like macros whose contents should not be touched by
clang-format, period. Clang-format can't automatically detect these
without a real compile context, so users will have to specify it
explicitly (it still beats clang-format off'ing at every invocation).
Defaults include "STRINGIZE", "PP_STRINGIZE", and "BOOST_PP_STRINGIZE".

Summary:
Previously, AST Matchers tests were using a custom way to run a test
with a specific C++ standard version. I'm migrating them to a shared
infrastructure to specify a Clang target from libClangTesting. I'm also
changing tests for AST Matchers to run in multiple language standards
versions, and under multiple triples that have different behavior with
regards to templates.
To keep the size of the patch manageable, in this patch I'm only
migrating one file to get the process started and get feedback on this
approach.
One caveat is that increasing the number of test configuration does
significantly increase the runtime of AST Matchers tests. On my machine,
the test runtime increases from 2.0 to 6.0s. I think it is worth the
improved test coverage.

the intrinsics were guarded on `__ARM_FEATURE_SVE_BF16` as the

guarded on the same macro an earlier error is triggered in the ACLE

C++ unqualified name lookup searches template parameter scopes
immediately after finishing searching the entity the parameters belong
to. (Eg, for a class template, you search the template parameter scope
after looking in that class template and its base classes and before
looking in the scope containing the class template.) This is complicated
by the fact that scope lookup within a template parameter scope looks in
a different sequence of places prior to reaching the end of the
declarator-id in the template declaration.
We used to approximate the proper lookup rule with a hack in the scope /
decl context walk inside name lookup. Now we instead compute the lookup
parent for each template parameter scope.
In order to get this right, we now make sure to enter a distinct Scope
for each template parameter scope, and make sure to re-enter the
enclosing class scopes properly when handling delay-parsed regions
within a class.

This better reflects what's going on (we're performing a substitution
while still inside a template), and in theory is more correct, but I've
not found a testcase where it matters in practice (largely because we
don't allow alias templates to be declared inside a function).
Fixed AST dumping of SubstNonTypeTemplateParm[Pack]Expr to demonstrate
that we're properly substituting through dependent alias templates. (We
can't deduce properly through these yet, but we can at least produce the
right input to template argument deduction.)

Add -fpch-instantiate-templates which makes template instantiations be

in order to handle its own instantiations). I can see 20-30% build
time saved with the few tests I've tried.
The change may reorder compiler output and also generated code, but
should be generally safe and produce functionally identical code.
There are some rare cases that do not compile with it,
such as test/PCH/pch-instantiate-templates-forward-decl.cpp. If
template instantiation bailed out instead of reporting the error,
these instantiations could even be postponed, which would make them
work.
Enable this by default for clang-cl. MSVC creates PCHs by compiling
them using an empty .cpp file, which means templates are instantiated
while building the PCH and so the .h needs to be self-contained,
making test/PCH/pch-instantiate-templates-forward-decl.cpp to fail
with MSVC anyway. So the option being enabled for clang-cl matches this.

The serialization of ConstantExpr has currently a number of problems:
- Some fields are just not serialized (ConstantExprBits.APValueKind and

- ASTStmtReader::VisitConstantExpr forgets to add the trailing APValue
to the list of objects to be destroyed when the APValue needs cleanup.
While we are at it, bring the serialization of ConstantExpr more in-line
with what is done with the other expressions by doing the following NFCs:
- Get rid of ConstantExpr::DefaultInit. It is better to not initialize
the fields of an empty ConstantExpr since this will allow msan to
detect if a field was not deserialized.
- Move the initialization of the fields of ConstantExpr to the constructor;
ConstantExpr::Create allocates the memory and ConstantExpr::ConstantExpr

The body of LambdaExpr is currently not properly serialized. Instead
LambdaExpr::getBody checks if the body has been already deserialized and if

the body of the LambdaExpr will be null.
The mutation in LambdaExpr::getBody was left because of another bug: it is not
true that the body of a LambdaExpr is always a CompoundStmt; it can also be
a CoroutineBodyStmt wrapping a CompoundStmt. This is fixed by returning a
Stmt * from getBody and introducing a convenience function getCompoundStmtBody
which always returns a CompoundStmt *. This function can be used by callers who
do not care about the coroutine node.
Happily all but one user of getBody treat it as a Stmt * and so this change
