add testcases for verifying ABI's integer size & align
It's easy to make some errors or some wrong assumptions
about size and alignment of basic types, certainly so when
taking in account the -m32, -m64 & -msize-llp64 flags and
the default behaviour on different arch & environments.
Try to catch these errors by adding a testcase for the
size & alignment of int, long, long long & void*.
