it ggc_alloc, drop second argument, never clear returned memory.
* ggc-common.c (ggc_alloc_string): Use ggc_alloc.
(ggc_alloc_cleared): New.
* ggc.h: Prototype ggc_alloc and ggc_alloc_cleared, not
ggc_alloc_obj. Remove ggc_alloc macro.
(ggc_alloc_rtx, ggc_alloc_rtvec, ggc_alloc_tree): Use ggc_alloc.
* rtl.c (rtvec_alloc): Clear the vector always.

obstack tricks (this routine is no longer a bottleneck).

* gengenrtl.c: Use puts wherever possible. Remove extra
newlines.
(gendef): Clear the first word of an RTX in the generator
function, irrespective of ggc_p. Initialize '0' slots to
NULL.

thin wrapper macro around obstack_alloc.
* stmt.c (expand_fixup): Use ggc_alloc.
