sparc.h (ASM_OUTPUT_MI_THUNK): Move %o7 through %g1 instead of save+restore. 

* sparc.h (ASM_OUTPUT_MI_THUNK): Move %o7 through %g1 instead of
save+restore.  Fix pic+big_offset delay slot.  Use "pic" case for
unix always, since we want to be able to thunk to functions in a
shared library from an application.
