st.c (new_size): use next_pow2 function
Reduces object size slightly on x86-64:
text data bss dec hex filename
2782359 22400 71880 2876639 2be4df ruby.orig
2781831 22400 71880 2876111 2be2cf ruby.pow2
And on 32-bit x86:
text data bss dec hex filename
2814751 12100 30552 2857403 2b99bb ruby.orig
2814051 12100 30552 2856703 2b96ff ruby.pow2
This is not a performance-critical function, but the
smaller icache footprint seems worth it.
