Instead of defining NO_REGS when IN_STG_CODE==0, define
NO_GLOBAL_REG_DECLS instead.

This means that in non-STG code we can still get at the values of
REG_R1 & co., even though the global register decls are turned off.
This is necessary because we sometimes need to set up different stack
layouts depending on REG_R1.
