[clang][Modules] Use strict comparison at build-session validation boundary (#197203)
The relocation check used `IFVT >= session` while input validation used
`IFVT > session`, silently skipping the relocation check when both
landed in the same truncated second. Share a single helper with the
strict comparison. This was noticed when the accompanying test was flaky
on green dragon macOS bot.
Also:
* Drop the test's `sleep 1` timing dependency by future-dating the
session timestamp directly.
* Remove the dead `touch %t/session.timestamp` lines in the
ClangScanDeps test (the scanner ignores the file's mtime).
hopefully resolves: rdar://173816745
[clang] implement CWG2064: ignore value dependence for decltype
The 'decltype' for a value-dependent (but non-type-dependent) should be known,
so this patch makes them non-opaque instead.
This patch also implements what's neceessary to allow overloading
on pure differences in instantiation dependence, making `std::void_t`
usable for SFINAE purposes.
This also readds a few test cases from da98651, which was a previous attempt
at resolving CWG2064.
Fixes #8740
Fixes #61818
Fixes #190388
[CIR] Fix problems with stale insert locations (#197296)
This change fixes three places where we were copying the builder rather
than getting a reference to it, leading to potential problems with
incorrect state, including insert locations. Two of these cases were
causing observable problems, and I'm adding regression tests for those.
The third doesn't seem to have caused any actual problems, but I'm
changing it to avoid potential problems in the future.

[BoundsSafety][NFC] Introduce LateParsedTypeAttribute for late-parsed type attributes (#192799)
Preparatory refactoring for llvm/llvm-project#179612. The new late
parsing approach needs a distinct data structure to carry
type-attribute-specific information through the late parsing pipeline,
separate from declaration-level late-parsed attributes.
- Add LateParsedTypeAttribute subtyping LateParsedAttribute
- Add ParseLexedTypeAttribute and LateTypeAttrParserCallback to Parser
- Extract the shared token setup, parsing, and cleanup logic from
ParseLexedCAttribute and ParseLexedTypeAttribute into a common
ParseLexedCAttributeTokens helper.
[DirectX][ObjectYAML] Add ILDN part support (#194508)
Add support for DXContainer ILDN part in the ObjectYAML pipeline so it
can be represented in structured YAML and round-tripped through
yaml2obj/obj2yaml.
ILDN part is meant to store the name of PDB file that contains shader
debug info.
[Instrumentor] Add unreachable support; unreachable stack trace printing
Allow to instrument unreachable and provide a use case to identify an
unreachable was reached.
biology/sra-tools: Patch out extraneous scripts
Build from source was installing scripts directly into /etc/profile.d
that are not even needed when installing from ports.
Also patched out some pip commands to silence poudriere warnings.

[Instrumentor] Add Alloca and Function support; stack usage example
This adds support for alloca instrumentation and function pre/post
instrumentation. Alloca support follows load/store support directly.
Functions require special care to determine the insertion points.
Together, we can showcase how the stack high watermark can be profiled,
see InstrumentorStackUsage.cpp.
[Instrumentor] Use the pass builder's FileSystem for reading files
In the IO sandbox, the old read calls caused the CI to fail. This
changes uses the PassBuilder's FileSystem the same way other passes
read files from disk (during CI).

[scudo] Add a generic allocation fuzzer. (#197317)
The fuzzer disabled memory tagging if supported since there is an
unknown problem with trying to create an allocator instance and doing
raw allocate/deallocate calls.

security/zeek: Update to 8.0.8
https://github.com/zeek/zeek/releases/tag/v8.0.8
This release fixes the following potential DoS vulnerability:
- A specially-crafted series of MIME headers sent via SMTP or HTTP
could cause Zeek to use large amounts of memory and potentially
crash.
This release fixes the following potential DoS vulnerability:
- Sqlite storage backends no longer potentially write data into a
single database file across multiple unrelated backend handles.
- A crash in the table code was fixed if reallocation failed while
resizing.

[DirectX][NFC] Move DICompileUnit conversion into DXILDebugInfo (#196451)
In #192574, I added logic for changing versioned language names to
unversioned language names, but did so directly in DXILBitcodeWriter.
This is better done in DXILDebugInfo instead so that, in a future
change, we can check the result of DXILDebugInfo in tests.
[Instrumentor] Add a global function regexp to limit the instrumentation
Only functions that match the "function_regex" will be instrumented,
or if they have the instrumentation attribute.
