[AArch64] Fix PR62178 testcase failures

The testcase for PR62178 has been failing for a while due to the pass
conditions being too tight, resulting in failures with -mcmodel=tiny:

	ldr	q2, [x0], 124
	ld1r	{v1.4s}, [x1], 4
	cmp	x0, x2
	mla	v0.4s, v2.4s, v1.4s
	bne	.L7

-mcmodel=small generates the slightly different:

	ldr	q1, [x0], 124
	ldr	s2, [x1, 4]!
	cmp	x0, x2
	mla	v0.4s, v1.4s, v2.s[0]
	bne	.L7

This is due to Combine merging a DUP instruction with either a load
or MLA - we can't force it to prefer one over the other.  However the
generated vector loop is fast either way since it generates MLA and
merges the DUP either with a load or MLA.  So relax the conditions
slightly and check we still generate MLA and there is no DUP or FMOV.

The testcase now passes - committed as obvious.
