BUG: put_var_into_stack() not handling SAVE_EXPR's

[grahams@rcp.co.uk]

Hi

In egcs-19980906/19980914 the routine put_var_into_stack() in
gcc/function.c tries to handle `decl' being a SAVE_EXPR as
evidenced by the calculation of `reg' and `decl_mode'.  But there
is a problem `decl' (which might be a SAVE_EXPR)  is passed
to DECL_NONLOCAL() macro.
