[SplitKit] In addDeadDef tolerate parent range that defines more lanes

Following on from D87757 "[SplitKit] Only copy live lanes", in
SplitEditor::addDeadDef, when we're checking whether the parent live
interval has a subrange defining the same lanes, tolerate the case
where the parent subrange defines a superset of the lanes. This can
happen when the child subrange comes from SplitEditor::buildCopy
decomposing a partial copy into a sequence of subreg copies that cover
the required lanes.

[AArch64] PAC/BTI code generation for LLVM generated functions

PAC/BTI-related codegen in the AArch64 backend is controlled by a set
of LLVM IR function attributes, added to the function by Clang, based
on command-line options and GCC-style function attributes. However,
functions, generated in the LLVM middle end (for example,
asan.module.ctor or __llvm_gcov_write_out) do not get any attributes
and the backend incorrectly does not do any PAC/BTI code generation.

This patch record the default state of PAC/BTI codegen in a set of
LLVM IR module-level attributes, based on command-line options:

* "sign-return-address", with non-zero value means generate code to
  sign return addresses (PAC-RET), zero value means disable PAC-RET.

* "sign-return-address-all", with non-zero value means enable PAC-RET
  for all functions, zero value means enable PAC-RET only for
  functions, which spill LR.

* "sign-return-address-with-bkey", with non-zero value means use B-key
  for signing, zero value mean use A-key.

This set of attributes are always added for AArch64 targets (as
opposed, for example, to interpreting a missing attribute as having a
value 0) in order to be able to check for conflicts when combining
module attributed during LTO.

Module-level attributes are overridden by function level attributes.
All the decision making about whether to not to generate PAC and/or
BTI code is factored out into AArch64FunctionInfo, there shouldn't be
any places left, other than AArch64FunctionInfo, which directly
examine PAC/BTI attributes, except AArch64AsmPrinter.cpp, which
is/will-be handled by a separate patch.

[Analyzer] Fix for `ExprEngine::computeObjectUnderConstruction()` for base and delegating consturctor initializers

For /C++/ constructor initializers `ExprEngine:computeUnderConstruction()`
asserts that they are all member initializers. This is not neccessarily
true when this function is used to get the return value for the
construction context thus attempts to fetch return values of base and
delegating constructor initializers result in assertions. This small
patch fixes this issue.

[CMake][CTE] Add "check-clang-extra-..." targets to test only a particular Clang extra tool

Create targets `check-clang-extra-clang-tidy`, `check-clang-extra-clang-query`
similar to how `check-clang-sema`, `check-clang-parser`, etc. are
auto-generated from the directory structure.

This allows running only a particular sub-tool's tests, not having to wait
through the entire `check-clang-tools` execution.

[PowerPC][LLD] Extend R2 save stub to support offsets of more than 26 bits

The R2 save stub will now support offsets up to 64 bits.

There are three cases that will be used.
1) The offset fits in 26 bits.
b <26 bit offset>
2) The offset does not fit in 26 bits but fits in 34 bits.
paddi r12, 0, <34 bit offset>, 1
mtctr r12
3) The offset does not fit in 34 bits. Since this is an R2 save stub we can use
the TOC in R2. We are not loading the offset but the actual address we want to
branch to.
addis r12, r2, <address in TOC lo>
ld r12 <address in TOC hi>(r12)
mtctr r12

In case 1) the stub is only 8 bytes while in cases 2) and 3) the stub will be
20 bytes.

[clang-format] Add a MacroExpander.

The MacroExpander allows to expand simple (non-resursive) macro
definitions from a macro identifier token and macro arguments. It
annotates the tokens with a newly introduced MacroContext that keeps
track of the role a token played in expanding the macro in order to
be able to reconstruct the macro expansion from an expanded (formatted)
token stream.

Made Token explicitly copy-able to enable copying tokens from the parsed
macro definition.
