2013-11-22  Trevor Saunders  <tsaunders@mozilla.com>

gcc/
	* vec.h (auto_vec): New class.
	* cfganal.c, cfgloop.c, cgraphunit.c, config/i386/i386.c, dwarf2out.c,
	function.c, genautomata.c, gimple.c, haifa-sched.c, ipa-inline.c,
	ira-build.c, loop-unroll.c, omp-low.c, ree.c, trans-mem.c,
tree-call-cdce.c, tree-eh.c, tree-if-conv.c, tree-into-ssa.c,
tree-loop-distribution.c, tree-predcom.c, tree-sra.c,
tree-sssa-forwprop.c, tree-ssa-loop-manip.c, tree-ssa-pre.c,
tree-ssa-reassoc.c, tree-ssa-sccvn.c, tree-ssa-structalias.c,
	tree-vect-loop.c, tree-vect-stmts.c: Use auto_vec and stack_vec as
	appropriate instead of vec for local variables.

	cp/
	* parser.c, semantics.c: Change some local variables from vec to
	auto_vec or stack_vec.
