[llvm-diff] Respect AllowAssumptions in diffCallSites (#203597)
diffCallSites always built an AssumptionContext, so call sites made
optimistic equivalence assumptions even when the caller disabled them.
This made matchForBlockDiff over-match, and the re-check in unify() then
hit the "structural differences second time around?" assertion.
Thread the caller's AssumptionContext into diffCallSites so call sites
honor the no-assumptions request like every other instruction kind.
Fixes #184133
Reland "[SSAF][Extractor] Make hard errors in PointerFlow and UnsafeBufferUsage Extractors quiet (#201953)" (#203602)
Reverted 7dcd1d2ad104c3f9748370a42dc775cd6e7e34dc and added '#ifndef
NDEBUG' guards for tests using 'llvm::setCurrentDebugType'.
Original message:
Hard errors were used in extractors during development to quickly
identify unsupported language constructs. This commit converts them to
DEBUG_WITH_TYPE so that these errors are silenced in release builds.
In addition, translating unsupported language constructs now silently
results in an empty EntityPointerLevelSet. The PointerFlowExtractor will
skip empty sets for either the source or the destination when building
edges to avoid an ill-formed edge set data structure.

[VPlan] Account for any-of costs in legacy cost model
Some VPlan transforms, like vectorizing fmin without fast-math,
introduce AnyOfs, which have costs assigned in the VPlan-based cost
model, but not the legacy cost model. Account for their cost like done
for other similar VPInstrctions, like EVL.
Fixes https://github.com/llvm/llvm-project/issues/185867.

[SimplifyCFG][DirectX] Honor target minimum lookup table element width (#203103)
fixes #202481
This change adds a `TTI::getMinimumLookupTableEntryBitWidth()` (default
`8`) and fold it
into SimplifyCFG's `NeededBitWidth` computation so targets can prevent
unsupported
narrow lookup tables. DirectX returns 32 (or 16 with native 16-bit
types) so tables
never narrow to the unsupported i8 type.

[VPlan] Compute URem via APInt in materializeVectorTripCount (#203604)
materializeVectorTripCount has a shortcut for scalable steps: if the
constant trip count is divisible by the maximum possible runtime step,
the vector trip count equals the trip count directly. This called
APInt::getZExtValue unconditionally, which asserts when the constant
value needs more than 64 bits.
Compute the URem in APInt to fix the crash.
[VPlan] Introduce m_SelectLike and use to support 2-operand blends. (#194729)
We should be able to treat 2-operand blends like select by most VPlan
code. Add a new m_SelectLike matcher and use in places that only use the
matcher to extract operands.
Overall this leads to a small number of improvements in RISCV (~10 files
changed in a large IR corpus) and 2 loops changed on AArch64 with
tail-folding forced.

vmimage.subr: Add ability to install src in VM image
In some cases having a src tree in a VM image is convenient
for development or debugging. Add a WITH_SRC variable,
which, when set, will cause the vm-release target to include
FreeBSD-set-src in the list of packages installed in an image.

[NFC][Support] Add test for inverted slash-agnostic matching (#203290)
Add a test case to GlobPatternTest to verify that inverted character
classes containing slashes (e.g. [^/] or [^\\]) behave correctly
under SlashAgnostic mode (i.e. they do not match either slash).

hosts.equiv.5: correct nits to fix `mandoc -T lint` issues
- Rename `.Nm .rhosts` to `.Nm rhosts` to match the MLINK for the
manpage.
- Use `.Pa` instead of `.Nm` when discussing the paths for `.rhosts` and
`hosts.equiv.5` for explicitness and clarity.

Fix API tests
* Reporting realtime shows stats on boot pool and so we should
expect it.
* pam / auth stack now properly reports in *audit* messages why the
authentication failed (minimally including PAM error code).
* harden our webshell tests
