gcc.target/i386/pr53533-[13].c: Adjust assembly scan

Before

1089d083117 Simplify (B * v + C) * D -> BD* v + CD when B,C,D are all INTEGER_CST.

the loop was

.L2:
	movl	(%rdi,%rdx), %eax
	addl	$12345, %eax
	imull	$-1564285888, %eax, %eax
	leal	-333519936(%rax), %eax
	movl	%eax, (%rsi,%rdx)
	addq	$4, %rdx
	cmpq	$1024, %rdx
	jne	.L2

There were 1 addl and 1 leal. 1 addq was to update the loop counter.  The
optimized loop is

.L2:
	imull	$-1564285888, (%rdi,%rax), %edx
	subl	$1269844480, %edx
	movl	%edx, (%rsi,%rax)
	addq	$4, %rax
	cmpq	$1024, %rax
	jne	.L2

1 addl is changed to subl and leal is removed. Adjust assembly scan to
check for 1 subl and 1 addl/addq as well as lea removal.

	* gcc.target/i386/pr53533-3.c: Likewise.
