Revert "[Clang] Propagate guaranteed alignment for malloc and others"llvmorg-14.0.0-rc1
The above change assumed that malloc (and friends) would always
allocate memory to getNewAlign(), even for allocations which have a
smaller size. This is not actually required by spec (a 1-byte
allocation may validly have 1-byte alignment).
Some real-world malloc implementations do not provide this guarantee,
and thus this optimization is breaking programs.
Fixes #53540
This reverts commit c2297544c04764237cedc523083c7be2fb3833d4.
