[PATCH] Makes softmmu compile with clang at HEAD

[Shu-Chun Weng]

With clang at HEAD, linking fails with "undefined symbol:
qemu_build_not_reached". It's because `store_helper` and
`helper_ret_stb_mmu` are mutually recursive and clang inlined latter
inside the former, making `store_helper` a recursive function and no
longer fully inlineable preventing constant propogation.
