i386: Rewrite ix86_indirect_branch_register logic

Rewrite ix86_indirect_branch_register logic with

(and (not (match_test "ix86_indirect_branch_register"))
     (original condition before r256662))

	* config/i386/predicates.md (constant_call_address_operand):
	Rewrite ix86_indirect_branch_register logic.
	(sibcall_insn_operand): Likewise.
