  Log Message:
  -----------
  [libc++] Mark libc++ deallocation helpers as noexcept (#110884)

They already can't throw exceptions and they are called from noexcept
functions, but they were not marked as noexcept. Depending on compiler
inlining, this might not make a difference or this might improve the
codegen a bit by removing the implicit try-catch block that Clang
generates around non-noexcept functions called from noexcept functions.

The original issue also mentioned that one occurrence of
std::allocator::deallocate was missing noexcept, however it has since
then been removed.

Fixes #66100
