gdbarch software_single_step returns VEC (CORE_ADDR) *
This patch changes gdbarch method software_single_step to return a
vector of addresses on which GDB should insert breakpoints, and don't
insert breakpoints. Instead, the caller of
gdbarch_software_single_step inserts breakpoints if the returned
vector is not NULL.
