[WebAssembly] GC constructor functions in otherwise unused archive objects

This allows `__wasilibc_populate_libpreopen` to be GC'd in more cases
where it isn't needed, including when linked from Rust's libstd.

Commit 84cc39c329f8d4910b8f558971d715f949ce1e94 by jezng
[llvm-readobj] Don't print out section names for STABS symbols

This diff is similar to what D71394 did for `llvm-objdump` -- it avoids
trying to look up a section name for STABS symbols, since some STABS
symbol types (like `N_OSO`) use the `n_sect` field to store other data
instead of a section index.

Ensure that InheritedAttrs are properly inherited along a redeclaration
chain for ObjCInterfaceDecls.

Only one such declaration can actually have attributes (the definition,
if any), but generally we assume that we can look for InheritedAttrs on
the most recent declaration.

Canonicalize declaration pointers when forming APValues.

References to different declarations of the same entity aren't different
values, so shouldn't have different representations.

reverted in 9a33f027ac7d73e14ae287e78ab554142d1cbc8f due to a bug caused

[lld][WebAssembly] Don't GC library objects under `--whole-archive`

Followup on which ignores
entire library objects when no symbols are used within them.
This is shouldn't apply with `--whole-archive` since this
is specified to treat them like direct object inputs.

Reland "[WebAssembly] Emulate v128.const efficiently""

This reverts commit 432e4e56d3d2, which reverted 542523a61a21. Two issues from
the original commit have been fixed. First, MSVC does not like when std::array
is initialized with only single braces, so this commit switches to using the
more portable double braces. Second, there was a subtle endianness bug that
prevented the original commit from working correctly on big-endian machines,
which has been fixed by switching to using endianness-agnostic bit twiddling
instead of type punning.
