This commit is causing build failures.

This patch reverts the lldb website revamp (eea88740

) since the `furo` theme
that we use is not installed on the publisher bot. The prevents other
website from getting there documentation updated.

D150312 added a TODO:

TODO: consider renaming the field `StartAtCycle` and `Cycles` to
`AcquireAtCycle` and `ReleaseAtCycle` respectively, to stress the
fact that resource allocation is now represented as an interval,
relatively to the issue cycle of the instruction.

This patch implements that TODO. This naming clarifies how to use these
fields in the scheduler. In addition it was confusing that `StartAtCycle` was
singular but `Cycles` was plural. This renaming fixes this inconsistency.

If the operands are proven to be non NaN, then the optimization can be applied
for all predicates.

We can apply the optimization for the following predicates for FMINNUM/FMAXNUM
(for quiet and signaling NaNs) and for FMINNUM_IEEE/FMAXNUM_IEEE if we can prove
that the operands are not signaling NaNs.

This commit enables modelling negation of native constraints.

This is accomplished through an attribute `isNegated` on the operations `pdl.apply_native_constraint` and `pdl_interp.apply_constraint` and according adjustments to the conversion in the ConvertPDLToPDLInterpPass.

If an end section basic block ends in an unconditional branch to its
fallthrough, BasicBlockSections will duplicate the unconditional branch.
This doesn't break x86, but it is a (slight) size optimization and more
importantly prevents AArch64 builds from breaking.

Ex:
```
bb1 (bbsections Hot):
  jmp bb2

bb2 (bbsections Cold):
  /* do work... */
```

After running sortBasicBlocksAndUpdateBranches():
```
bb1 (bbsections Hot):

  jmp bb2

When loading (transitively) imported AST file, `ModuleManager::addModule()` first checks it has the expected signature via `readASTFileSignature()`. The signature is part of `UNHASHED_CONTROL_BLOCK`, which is placed at the end of the AST file. This means that just to verify signature of an AST file, we need to skip over all top-level blocks, paging in the whole AST file from disk. This is pretty slow.

This patch moves `UNHASHED_CONTROL_BLOCK` to the start of the AST file, so that it can be read more efficiently. To achieve this, we use dummy signature when first emitting the unhashed control block, and then backpatch the real signature at the end of the serialization process.

This speeds up dependency scanning by over 9% and significantly reduces run-to-run variability of my benchmarks.

Depends on D158572.

This patch replaces absolute offsets into the input files block with offsets relative to the block start. This makes the whole section "relocatable". I confirmed all other uses of `GetCurrentBitNo()` are turned into relative offsets before being serialized into the AST file.

The patch adds parser, MCExpr, and emitter support for the authenticated
pointer auth relocation.

In assembly, this is expressed using:
  .quad <symbol>@AUTH(<key>, <discriminator> [, addr])
For example:
  .quad _g3@AUTH(ib, 1234, addr)

The optional 'addr' specifier represents whether the generated pointer
authentication code will also include address diversity (by blending the
address of the storage location of the relocated pointer with the
user-specified constant discriminator).

The @AUTH expression lowers to R_AARCH64_AUTH_ABS64 ELF relocation.

The signing schema is encoded in the place of relocation to be applied
as follows:

```
| 63                | 62 | 61:60 | 59:48 |  47:32        | 31:0   |
| ----------------- | -- | ----- | ----- | ------------- | ------ |
| address diversity | 0  | key   | 0     | discriminator | addend |
```

When using `clangd` for cross-compiled projects, it's necessary to use the `--query-driver` flag so that `clangd` can extract the compiler's built-in header paths. However, there's no such flag for `clangd-indexer` so we're unable to build a working static index for these projects.

This patch adds a `--query-driver` flag to `clangd-indexer` for this scenario.

I saw some tests under `clang-tools-extra/clangd/test/` but I think the cross-compilation case is a bit more complex to test. Let me know if you'd like me to look into this further.

We were testing for an exact match of zero bits which isn't necessary (we don't care if lower bits are zero) - by inspection as its proven tricky to get a decent test case.

Noticed while clearing up D155472 regressions

Same fix as 8a62d6ba: We need to make sure that the supports-JIT check uses
the same JIT config that will be used in the actual test.

As a side effect, introduce AtomicExpr::getOpAsString() to dump the
AtomicOp string representation.

Looks like this test was trying to check if two shifts were combined, but it
was accidentally using the insertelement instead of the splat.

This patch brings a fresh coat of paint to the LLDB website.

This uses the `furo` theme from the suggested theme list, adds some
changes to the css to make it use the full browser window width and
removes the table of contents since the theme generates it automatically.

This patch also rewrites the tables for "GDB to LLDB command map" to
convert them from raw HTML to native inlined code blocks.

To generate the website, make sure you install the theme first with
`pip install furo`, enable sphinx in the cmake invocation` then run
`ninja docs-lldb-html`
