Subject: i386.md (shift patterns): Use (TARGET_SHIFT1 || optimize_size) to
 decide whether emit the short opcode.

	* i386.md (shift patterns): Use (TARGET_SHIFT1 || optimize_size) to
	decide whether emit the short opcode.
	* i386.h (x86_shift1): Declare.
	(TARGET_SHIFT1): New macro.
	* i386.c (x86_shift1): New global variable.

	* toplev.c (rest_of_compilation): Call find_basic_block pre-loop unconditionally;
	make loop to rebuild CFG; kill unnecesary find_basic_block calls;
	kill compute_bb_for_insn call.
	* cfgbuild.c (find_basic_blocks): Kill compute_bb_for_insn call.
	* haifa-sched.c (sched_init): Likewise.
	* ssa-ccp.c (ssa_const_prop): Likewise.
	* ssa-dce.c (ssa_eliminate_dead_code): Likewise.
