Allow building with `CFLAGS="-O0"`
If compiled with -O0, gcc doesn't do any stack frame coalescing
and -Wframe-larger-than=1024 is triggered in debug mode.
Starting with gcc 4.8, new opt level -Og is introduced for debugging, which
does not trigger this warning.
Fix bench zio size, using SPA_OLD_MAXBLOCKSHIFT
