Richard Smith 8ac5c746fc Don't elide the use of the thread wrapper for a thread_local constinit
variable with non-trivial destruction.

We still need to invoke the thread wrapper to trigger registration of
the destructor call on thread shutdown.

Richard Smith 9f42a1231e [c++20] Add a C++20 version of the existing turing machine test.
Unlike the C++11 version, this one uese mutable state and dynamic

Erich Keane a60ef724b4 Fix failure caused by r373247
I incorrectly thought that the 'isLambda' check never fired, so when
splitting up a helper function, I lost the 'nullptr' return value.
ClangD Hover functionality apparently uses this, so the Unittest caught
that.

This patch correctly propogates the nullptr from the helper function.

Erich Keane 5c2c60d2fc Teach CallGraph to look into Generic Lambdas.
CallGraph visited LambdaExpr by getting the Call Operator from
CXXRecordDecl (LambdaExpr::getCallOperator calls
CXXRecordDecl::getLambdaCallOperator), which replaced generic lambda
call operators with the non-instantiated FunctionDecl.  The result was
that the CallGraph would only pick up non-dependent calls.

This patch does a few things:
1- Extend CXXRecordDecl to have a getDependentLambdaCallOperator, which
will get the FunctionTemplateDecl, rather than immediately getting the
TemplateDecl.
2- Define getLambdaCallOperator and getDependentLambdaCallOperator in
terms of a common function.
3- Extend LambdaExpr with a getDependentCallOperator, which just calls
the above function.
4- Changes CallGraph to handle Generic LambdaExprs.

Teresa Johnson 57dbfe194c [Clang] Use -main-file-name for source filename if not set
-main-file-name is currently used to set the source name used in debug
information.

If the source filename is "-" and -main-file-name is set, then use the
filename also for source_filename and ModuleID of the output.

The argument is generally used outside the internal clang calls when
running clang in a wrapper like icecc which gives the source via stdin
but still wants to get a object file with the original source filename
both in debug info and IR code.

Richard Smith 1e8c0850b1 For now, disallow lifetime-extended temporaries with non-trivial (but
constexpr) destructors from being used in the values of constexpr
variables.

The standard rules here are unclear at best, so rejecting the
problematic cases seems prudent. Prior to this change, we would fail to
run the destructors for these temporaries, even if they had
side-effects, which is certainly not the right behavior.

Sergey Dmitriev 4b343fd84c [Clang][OpenMP Offload] Create start/end symbols for the offloading entry table with a help of a linker
Linker automatically provides __start_<section name> and __stop_<section name> symbols to satisfy unresolved references if <section name> is representable as a C identifier (see https://sourceware.org/binutils/docs/ld/Input-Section-Example.html for details). These symbols indicate the start address and end address of the output section respectively. Therefore, renaming OpenMP offload entries section name from ".omp.offloading_entries" to "omp_offloading_entries" to use this feature.

This is the first part of the patch for eliminating OpenMP linker script (please see https://reviews.llvm.org/D64943).

Yitzhak Mandelbaum db24ef509e [libTooling] Transformer: refine `SourceLocation` specified as anchor of changes.
Summary: Every change triggered by a rewrite rule is anchored at a particular
location in the source code.  This patch refines how that location is chosen and
defines it as an explicit function so it can be shared by other Transformer
implementations.

This patch was inspired by a bug found by a clang tidy, wherein two changes were
anchored at the same location (the expansion loc of the macro) resulting in the
discarding of the second change.

Martin Storsjo 71decf841c [clang] [AST] Treat "inline gnu_inline" the same way as "extern inline gnu_inline" in C++ mode
This matches how GCC handles it, see e.g. https://gcc.godbolt.org/z/HPplnl.
GCC documents the gnu_inline attribute with "In C++, this attribute does
not depend on extern in any way, but it still requires the inline keyword
to enable its special behavior."

The previous behaviour of gnu_inline in C++, without the extern
keyword, can be traced back to the original commit that added
support for gnu_inline, SVN r69045.
