Hi,

It appears as though the length of the vec_pack_trunc was incorrectly
not set to anything. This has been fixed now at 8 bytes. I have also
taken the oppurtunity to remove the \n\t and replace it with a
\; instead.

I'll commit this to both trunk and 4.6 branch after a round of sanity
checking.

cheers
Ramana

	PR target/48454
	* config/arm/neon.md (vec_pack_trunc<mode>): Set the lengths
	correctly for the case with Quad vectors.
