math: fix pow signed shift ub
j is int32_t and thus j<<31 is undefined if j==1, so j is changed to uint32_t locally as a quick fix, the generated code is not affected. (this is a strict conformance fix, future c standard may allow 1<<31, see DR 463. the bug was inherited from freebsd fdlibm, the proper fix is to use uint32_t for all bit hacks, but that requires more intrusive changes.) reported by Daniel Sabogal
