[Bug debug/43329] Early inlining causes suboptimal debug info

The problem is that with early inlining, method (&inst, 24) call is inlined
into
call function, then at the end of einline during arrg3 and min vars in call are
removed as unused locals by remove_unused_locals (the inline asm uses 24
directly, so arrg3 is only referenced in DEBUG stmts, not sure why min didn't
have any DEBUG stmts even generated).  Then when in the normal inliner call is
inlined into main, both arrg3 and min are non-localized because their var_ann
is NULL.  And for non-localized vars dwarf2out isn't able to find the
dwarf2out_var_location tracked values.
