  Log Message:
  -----------
  [libc++] Fix noexcept behaviour of operator new helper functions  (#74337)

This patch removes the noexcept specifier introduced in #69407 since the
Standard allows a new handler to throw an exception of type bad_alloc 
(or derived from it). With the noexcept specifier on the helper
functions, we would immediately terminate the program.

The patch also adds tests for the case that had regressed.
