[tree-ssa]: Patch: bootstrap regression fix


This patch
2003-12-17  Jan Hubicka  <jh@suse.cz>

* tree-inline.c (estimate_num_insns_1): Check that all nodes are
known; add missing nodes; fix MODIFY_EXPR


broke bootstrap on Darwin; the rs6000 files do not define MOVE_RATIO specially.
According to the doc they don't have to. This moves the default definition from
expr.c to expr.h. Bootstrapped. OK?


(Apple's mailer may screw up the long lines below, although they look all right to me;
I promise the change is a simple cut-and-paste.)
