Revert "MdePkg: avoid __builtin_unreachable() on GCC v4.4"
This reverts commit 357cec385d4f ("MdePkg: avoid __builtin_unreachable()
on GCC v4.4", 2016-07-21).
We've removed BaseTools support for GCC44..GCC47, therefore we need not
catch the GCC44 corner case for __builtin_unreachable().
No GCC44..GCC47 references remain under MdePkg after this patch.
