Subject: [PATCH 22/27] codegen_ssa: pack small const aggregates into immediate
 stores

For small repr(C) aggregates with padding, direct constant
initialization can still lower into field-wise construction plus
memcpy. That leaves the backend to rediscover that the whole object
is a single constant byte pattern.

This is especially visible for non-zero constant aggregates. Instead
of materializing them as separate field stores, we want codegen_ssa to
emit the packed value directly. For example, a value like

    InnerPadded { a: 0, b: 1, c: 0 }

can otherwise lower to something like

    store i16 0, ptr %val, align 4
    store i8 1, ptr %val_plus_2, align 2
    store i32 0, ptr %val_plus_4, align 4
    call void @llvm.memcpy(..., ptr %val, ...)

while this change produces

    store i64 65536, ptr %val, align 4
    call void @llvm.memcpy(..., ptr %val, ...)

Why not solve this in LLVM?

At the problematic lowering point, rustc still knows that the MIR
aggregate is small and fully constant. LLVM only sees a lowered stack
temporary built from per-field stores and then copied out. Recovering
that packed constant there would require rediscovering front-end
aggregate semantics after lowering, so emitting the packed store in
rustc is the simpler and more local fix.

Why not keep the previous typed-copy approach?

An earlier approach zeroed padding on typed copies whose source could
be traced back to a constant assignment. That helped some cases, but it
also widened the optimization to runtime copy paths and could introduce
extra runtime stores purely to maintain padding knowledge. That is not
an acceptable tradeoff here.

Keep the scope narrow instead: only handle direct MIR aggregates whose
fields are all constants, and pack them according to the target
endianness before emitting a single integer store.

Add a focused codegen test covering the original PR 157690 entry
points together with non-zero constant cases. The test uses
-Cno-prepopulate-passes so it checks the immediate-store shape directly
at rustc codegen time, instead of depending on later LLVM store
merging.

Subject: [PATCH 24/27] resolve: fix effective visibilities for items in
 ambiguous glob sets

Since PR 154149, when one item is glob-imported into a module twice with
different visibilities, the first-arrived declaration stays in the
resolution slot and the most visible declaration of the ambiguous glob
set is only recorded in `ambiguity_vis_max`. `DeclData::vis()` returns
the max, so name resolution, metadata reexports and
`cross_crate_inlinable` export the item at the maximum visibility, but
`set_bindings_effective_visibilities` walked only the slot-resident
declaration's reexport chain. When the restricted route arrives first,
the definition's effective visibility caps at the restricted
visibility while the item is still exported: spurious dead_code, the
item missing from reachable_set, should_encode_mir returning false, and
downstream crates failing with "missing optimized MIR" (a 1.96.1 ->
1.97.0 stable-to-stable regression).

Generalize the one-level `ambiguity_vis_max` update that PR 154149 added
in `update_import` (to keep the most visible import from being reported
as unused) into a walk of that declaration's whole reexport chain:
extract the chain walk into `update_decl_chain` and recurse into
`ambiguity_vis_max` at every hop, so the most visible declaration
drives the effective visibility of everything on its route, including
the final definition. Updates are monotone, so the dual walk is
order-independent. The `ambiguous_import_visibilities` lint and the
PR 156284 diagnostic suppression are untouched.
