Revert bogus LIT_ALIGN commit from 2015.

This reverts commit 0343c6f32c5bd8335e88595cb9d23506625b2586.

I don't see evidence that the claim in the commit is true:
that wide literals are not four-byte-aligned on Darwin in
spite of sizeof(wchar_t) being 4. Not even with the old clang
in my old VM where I first thought I discovered this.

* configure: do not set up LIT_ALIGN == 2 for Darwin.

* lib.h (litptr): Remove LIT_ALIGN < 4 && SIZEOF_WCHAR_T == 4
case.

* HACKING: Undocument bogus claim.
