Jan Svoboda 4545813b17 [clang][cli] NFC: Rename marshalling multiclass

Krystian Kuzniarek 6ca52815fb [clang-format][PR47290] Add ShortNamespaceLines format option
clang-format documentation states that having enabled
FixNamespaceComments one may expect below code:

c++
namespace a {
foo();
}

to be turned into:

c++
namespace a {
foo();
} // namespace a

In reality, no "// namespace a" was added. The problem was too high
value of kShortNamespaceMaxLines, which is used while deciding whether
a namespace is long enough to be formatted.

As with 9163fe2, clang-format idempotence is preserved.

Nico Weber 52b8e10597 [libclang] Remove LIBCLANG_INCLUDE_CLANG_TOOLS_EXTRA

Jakub Budiský 2a42c759ae [clang-format] [PR19056] Add support for access modifiers indentation
Adds support for coding styles that make a separate indentation level for access modifiers, such as Code::Blocks or QtCreator.

The new option, `IndentAccessModifiers`, if enabled, forces the content inside classes, structs and unions (“records”) to be indented twice while removing a level for access modifiers. The value of `AccessModifierOffset` is disregarded in this case, aiming towards an ease of use.

======
The PR (https://bugs.llvm.org/show_bug.cgi?id=19056) had an implementation attempt by @MyDeveloperDay already (https://reviews.llvm.org/D60225) but I've decided to start from scratch. They differ in functionality, chosen approaches, and even the option name. The code tries to re-use the existing functionality to achieve this behavior, limiting possibility of breaking something else.

Dan Liew 5d64dd8e3c [Clang][ASan] Introduce `-fsanitize-address-destructor-kind=` driver & frontend option.
The new `-fsanitize-address-destructor-kind=` option allows control over how module
destructors are emitted by ASan.

The new option is consumed by both the driver and the frontend and is propagated into
codegen options by the frontend.

Both the legacy and new pass manager code have been updated to consume the new option
from the codegen options.

It would be nice if the new utility functions (`AsanDtorKindToString` and
`AsanDtorKindFromString`) could live in LLVM instead of Clang so they could be
consumed by other language frontends. Unfortunately that doesn't work because
the clang driver doesn't link against the LLVM instrumentation library.

David Crook 039f79c78c [SEMA] Added warn_decl_shadow support for structured bindings
https://bugs.llvm.org/show_bug.cgi?id=40858

CheckShadow is now called for each binding in the structured binding to make sure it does not shadow any other variable in scope. This does use a custom implementation of getShadowedDeclaration though because a BindingDecl is not a VarDecl

Added a few unit tests for this. In theory though all the other shadow unit tests should be duplicated for the structured binding variables too but whether it is probably not worth it as they use common code. The MyTuple and std interface code has been copied from live-bindings-test.cpp

Fangrui Song 34b60d8a56 Add -fbinutils-version= to gate ELF features on the specified binutils version
There are two use cases.

Assembler
We have accrued some code gated on MCAsmInfo::useIntegratedAssembler().  Some
features are supported by latest GNU as, but we have to use
MCAsmInfo::useIntegratedAs() because the newer versions have not been widely
adopted (e.g. SHF_LINK_ORDER 'o' and 'unique' linkage in 2.35, --compress-debug-sections= in 2.26).

Linker
We want to use features supported only by LLD or very new GNU ld, or don't want
to work around older GNU ld. We currently can't represent that "we don't care
about old GNU ld".  You can find such workarounds in a few other places, e.g.
Mips/MipsAsmprinter.cpp PowerPC/PPCTOCRegDeps.cpp X86/X86MCInstrLower.cpp
AArch64 TLS workaround for R_AARCH64_TLSLD_MOVW_DTPREL_* (PR ld/18276),
R_AARCH64_TLSLE_LDST8_TPREL_LO12 (https://bugs.llvm.org/show_bug.cgi?id=36727 https://sourceware.org/bugzilla/show_bug.cgi?id=22969)

Mixed SHF_LINK_ORDER and non-SHF_LINK_ORDER components (supported by LLD in D84001;
GNU ld feature request https://sourceware.org/bugzilla/show_bug.cgi?id=16833 may take a while before available).
This feature allows to garbage collect some unused sections (e.g. fragmented .gcc_except_table).

This patch adds `-fbinutils-version=` to clang and `-binutils-version` to llc.
It changes one codegen place in SHF_MERGE to demonstrate its usage.
`-fbinutils-version=2.35` means the produced object file does not care about GNU
ld<2.35 compatibility. When `-fno-integrated-as` is specified, the produced
assembly can be consumed by GNU as>=2.35, but older versions may not work.

`-fbinutils-version=none` means that we can use all ELF features, regardless of
GNU as/ld support.

Both clang and llc need `parseBinutilsVersion`. Such command line parsing is
usually implemented in `llvm/lib/CodeGen/CommandFlags.cpp` (LLVMCodeGen),
however, ClangCodeGen does not depend on LLVMCodeGen. So I add
`parseBinutilsVersion` to `llvm/lib/Target/TargetMachine.cpp` (LLVMTarget).
