Specifying --headers is equivalent to setting --file-headers,
--program-headers and --section-headers at the same time.
The existent test case uses a precompiled object and doesn't test the

Similarly as for pointers, even for integers a == b is usually false.

This lets basic AST-consuming actions be defined outside clangdserver.
(it essentially exposes TUScheduler::runWithAST).
Two use cases for now:
- replace ClangdServer::dumpAST, which doesn't really belong in the public
interface (a followup patch will do this)
- allow embedders to add/experiment with extra features
(e.g. I know some who want to try crazy AST+ML code completion...)
Maybe in the future we should use this sort of mechanism to make ClangdServer
less of a monolith, but that's not in scope for now.
This would probably require a richer and more carefully-thought-out API.

In DAGTypeLegalizer::GenWidenVectorStores the algorithm assumes it only
ever deals with fixed width types, hence the offsets for each individual
store never take 'vscale' into account. I've changed the main loop in
that function to use TypeSize instead of unsigned for tracking the
remaining store amount and offset increment. In addition, I've changed
the loop to use the new IncrementPointer helper function for updating
the addresses in each iteration, since this handles scalable vector
types.
Whilst fixing this function I also fixed a minor issue in
IncrementPointer whereby we were not adding the no-unsigned-wrap flag
for the add instruction in the same way as the fixed width case does.
Also, I've added a report_fatal_error in GenWidenVectorTruncStores,
since this code currently uses a sequence of element-by-element scalar
stores.
I've added new tests in
CodeGen/AArch64/sve-intrinsics-stores.ll
CodeGen/AArch64/sve-st1-addressing-mode-reg-imm.ll
for the changes in GenWidenVectorStores.

In narrowExtractedVectorLoad there is an optimisation that tries to
combine extract_subvector with a narrowing vector load. At the moment
this produces warnings due to the incorrect calls to
getVectorNumElements() for scalable vector types. I've got this
working for scalable vectors too when the extract subvector index
is a multiple of the minimum number of elements. I have added a
new variant of the function:
MachineFunction::getMachineMemOperand
that copies an existing MachineMemOperand, but replaces the pointer
info with a null version since we cannot currently represent scaled
offsets.
I've added a new test for this particular case in:
CodeGen/AArch64/sve-extract-subvector.ll

Currently only two test failures remain on Sparc, both
`sparcv9-sun-solaris2.11` and `sparc64-unknown-linux-gnu`:
LLVM :: DebugInfo/Generic/debug-label-inline.ll
LLVM :: Linker/subprogram-linkonce-weak.ll
They seem related in that debug info isn't generated for instruction
bundles (like `retl+add` in the delay slot).
I've filed separate bugs for both files (Bug 47129 and 47131), though it's
probably the same issue.
This patch `XFAIL`s the tests.
Tested on `sparcv9-sun-solaris2.11` and `amd64-pc-solaris2.11`.

When building on `sparc64-unknown-linux-gnu`, I found that a large number
of `SanitizerCommon-asan-sparc*-Linux` tests were `FAIL`ing, like
SanitizerCommon-asan-sparc-Linux :: Linux/aligned_alloc-alignment.cpp
[...]
SanitizerCommon-asan-sparcv9-Linux :: Linux/aligned_alloc-alignment.cpp
[...]
many of them due to
fatal error: error in backend: Function "_Z14User_OnSIGSEGViP9siginfo_tPv": over-aligned dynamic alloca not supported.
which breaks ASan on Sparc. Currently ASan is only built for the benefit
of `gcc` where it does work. However, when enabling the compilation in
`compiler-rt` to make certain it continues to build, I missed
`compiler-rt/test/sanitizer_common` when disabling ASan testing on Sparc
(it's not yet enabled on Solaris).
This patch fixes the issue.
Tested on `sparcv9-sun-solaris2.11` with the `sanitizer_comon` testsuite enabled.

We do that because:
* Big tests generated big tree dumps that could hardly serve as documentation.
* In most cases the tests didn't share setup, thus there was not much addition in lines of code.
We split tests for:

* `NestedBinaryOperator`
* `UserDefinedBinaryOperator`
* `UserDefinedPrefixOperator`
* `QualifiedId`

This is motivated by tooling (clangd, libclang etc) - headers without

The other use -x c-header cases (PCH/modules) are nonstandard anyway and this

References to symbols in dylibs work very similarly regardless of
whether the symbol is a TLV. The main difference is that we have a
separate `__thread_ptrs` section that acts as the GOT for these
thread-locals.
We can identify thread-locals in dylibs by a flag in their export trie
entries, and we cross-check it with the relocations that refer to them
to ensure that we are not using a GOT relocation to reference a
thread-local (or vice versa).
