Currently runtime/internal/sys bit-manipulation functions are aliased to math/bits functions, which are intrinsified. Unfortunately these aliases are declared before the intrinsified versions are generated, resulting in the generic version of the code being copied over. This change moves the aliases for bit operations in runtime/internal/sys after the addF calls to generate those intrinsics in SSA, so that the intrinsified SSA representation of those functions actually get copied over. This should improve the overall performance of the runtime (especially the page allocator) since these bit operations will actually be intrinsified now.
