Fix memory leak in selftest::test_expansion_to_rtl
"make selftest-valgrind" shows:
187 bytes in 1 blocks are definitely lost in loss record 567 of 669
at 0x4A081D4: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)

The allocation in question is:
crtl->emit.regno_pointer_align
= XCNEWVEC (unsigned char, crtl->emit.regno_pointer_align_length);
This patch fixes this leak (and makes the output of
"make selftest-valgrind" clean) by calling free_after_compilation at the
end of the selftest in question.
gcc/ChangeLog:
* function-tests.c (selftest::test_expansion_to_rtl): Call
free_after_compilation.
