Fix PR 10153: tail recusion for vector types.

The problem here is we try to an initialized value
from a scalar constant. For vectors we need to do
a vect_dup instead.  This fixes that issue by using
build_{one,zero}_cst instead of integer_{one,zero}_node
when calling create_tailcall_accumulator.

Changes from v1:
* v2: Use build_{one,zero}_cst and get the correct type before.

OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions.

gcc/ChangeLog:

	PR tree-optimization/10153
	* tree-tailcall.c (create_tailcall_accumulator):
	Don't call fold_convert as the type should be correct already.
	(tree_optimize_tail_calls_1): Use build_{one,zero}_cst instead
	of integer_{one,zero}_node for the call of create_tailcall_accumulator.

gcc/testsuite/ChangeLog:

	PR tree-optimization/10153
	* gcc.c-torture/compile/pr10153-1.c: New test.
	* gcc.c-torture/compile/pr10153-2.c: New test.
