Remove incorrect check in AC_CHECK_SIZEOF
* lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF):
When the size or alignment cannot be determined, do not fail if
ac_cv_type_$1 is yes, as there’s no guarantee that ac_cv_type_$1
is defined, and failure here would contradict the documentation
that the size or alignment is 0 when sizeof($1)/alignof($1) cannot
be compiled. The test for ac_cv_type_$1 made sense long ago when
it was checked for in these macros, but the test has not made
sense for many years.
