[clang][modules] Deserialize submodules lazily (#194968)
This PR implements on-demand deserialization of `Module` objects from
PCM files. This is motivated by dependency scanning, where eager
deserialization of submodules turns out to be very expensive and
typically unnecessary. The core of this patch is the introduction of
`ModuleRef`, which may either be a pointer to `Module`, a pointer to new
`ExternalSubmoduleSource` (implemented by `ASTReader`) and
`serialization::SubmoduleID`, both, or none (null). Dereferencing
`ModuleRef` ensures the `Module` is deserialized if possible.
This replaces `ASTReader::UnresolvedModuleRefs` and changes the
structure of a PCM file a bit, most importantly introducing new
`SUBMODULE_CHILD` record that enables hooking up the laziness into the
qualified by-name lookup that uses `Module::SubModuleIndex`.
This speeds up dependency scanning by ~5.5%.
[mlir][vector] Implement IndexedAccessOpInterface for load, store, etc. (#196216)
This commit adds simple (not trying to account for unit dimensions that
could be cast away) implementations of IndexedAccessOpInterface to
low-level vector operations like vector.load and vector.store,
eliminating the need for the old-style code in FoldMemRefAliasOps.cpp.
After this commit, it'll be possible to migrate all the other
memref-rewriting passes (ExpandAddressComputation and FlattenMemRefs) to
use the interface, taking a bunch of dialect dependencies off of
memref/transforms.

sysutils/firstboot-pkg-upgrade: New port
Introduce an rc.d service to upgrade all packages on first boot,
ensuring cloud images are deployed with no known vulnerabilities. By
default, it will patch everything from all enabled repos, and record
this in syslog. It accepts an optional additional line that specifies
a list of space-separated specific repos to limit the upgrade to.
Note specifying bogus repos results in the upgrade aborting,
it will log This and will not try to not run again.

Symbol names on arm64 can have an extra char on front of name (#194937)
My previous change (https://github.com/llvm/llvm-project/pull/192132)
didn't work with aarch64. The symbol name has the \x01 on the front and
the greps fail. Update the expression for the grep to allow for that
char.
Sorry about that. The original grep with `@pipe` also fails on aarch64 &
macos. The negative test those greps are doing will always pass on
aarch64 & macos. That should be looking for the updated symbol name too.
sys/time: appease gcc -Wtype-limits
In environments where time_t is 32 bits, including the 32-bit library
build on amd64, the overflow being tested for cannot happen, and gcc
complains with -Wtype-limits, causing the gcc build to fail. Work
around this by ifdef'ing out the saturation code on i386.

Make "make update-packages" idempotent
If the user runs "make update-packages" without bumping BRANCH, then it
isn't possible to copy packages from the old location to the new one
(because the two locations are the same). So just skip that step.

[AMDGPU] Pre-commit unit test for RP tracking reset/advance behavior
This adds a new AMDGPU unit test file for testing the behavior of
`GCNRPTracker` and its related classes. The two test showcase confusing
return value and behavioral semantics for variants of the advance and
reset functions, which will be clarified in a follow up commit.
This also moves some common test helpers from other AMDGPU unit tests to
the `AMDGPUUnitTests` TU to avoid repetition between unit tests.
[SLP][X86] Forward gather VL to getShuffleCost for broadcast-of-load
ShuffleCostEstimator::finalize() emits the user-visible final shuffle on
top of the gather node, but it called the local createShuffle helper
without forwarding the gathered scalars. Consequently
X86TTIImpl::getShuffleCost(), which folds vbroadcast{ss,sd} of a
load into TCC_Free under AVX/AVX2, could not see the underlying load
and overestimated the cost of the splat permutation by one unit,
occasionally dropping a profitable vectorization.
Also, modified the TTI cost estimation to handle correctly the cost for
the scalar code before actual admission of the vector broadcast.
