Lack of any .toc section alignment causes kexec and kdump failure
when linking without the usual linker script.  This of course is
really a kexec-tools error, but it is also true that .toc ought to
always be word aligned.

Under specific circumstances for Ada programs, such as in the testcase
this change adds, the DWARF back-end currently crashes because of

PR 70687 reports a case where combine.c mishandles integer modes
wider than unsigned HOST_WIDE_INT.  I don't have a testcase since
the PR is just pointing out the hole.

Also, I think a ZERO_EXTEND of a vector mode could in principle satisfy
the subreg condition but wouldn't be equivalent to an AND.  E.g.:

      (zero_extend:V4DI (subreg:V4SI (reg:V4DI R) 0))

Tested on x86_64-linux-gnu.
