  [clang][WebAssembly] Link crt1 even in case of -shared

This allows -mexec-model=reactor -shared produces a library module
with _initialize entrypoint, which is preferrable over __wasm_call_ctors.

  Revert "Reland [clang] Canonicalize system headers in dependency file when -canonical-prefixes" (#71697)

This reverts commit 578a4716f549167165a2ec3bac89c86706136d4e.

This causes multiple issues. Compile time slowdown due to more path
canonicalization, and weird behavior on Windows.

Will reland under a separate flag `-f[no-]canonical-system-headers` to
match gcc in the future and further limit when it's passed by default.

Fixes #70011.

  Log Message:
  -----------
  [libc++] Use correct size for deallocation of arrays in shared_ptr (#68233)

Fixes #68051.

Current implementation passes the number of `_AlignedStorage` objects
when it calls to `allocate` and the number of **bytes** on `deallocate`.
This only applies to allocations that allocate control block and the
storage together, i.e. `make_shared` and `allocate_shared`.

Found by ASan under Clang combined with `-fsized-deallocation`.

  Log Message:
  -----------
  Use the correct namespace for looking up matching operator!= (#68922)

`S.getScopeForContext` determins the **active** scope associated with
the given `declContext`.
This fails to find the matching `operator!=` if candidate `operator==`
was found via ADL since that scope is not active.

Instead, just directly lookup using the namespace decl of `operator==`

Fixes #68901
