Unfortunately the aarch64/pr112406.c was reduced too much and is rejected
since the switch to modern C patchset.

The following patch fixes that, I've verified the testcase
before/after the changes still ICEs in r14-5563 and doesn't with
r14-5564 and after the changes compiles fine with even latest trunk.
Everything admittedly with a cross-compiler, but that shouldn't change
anything.

Ok for trunk?

Note, one of the modern C changes is that at least when people use
cvise/creduce/delta scripts which ensure no further errors are introduced
during the reduction then expected originally such reductions will not
appear anymore.

	* gcc.target/aarch64/pr112406.c (MagickPixelPacket): Add missing
	semicolon.
	(GetImageChannelMoments_image): Avoid using implicit int.
	(SetMagickPixelPacket): Use void return type instead of implicit int.
	(GetImageChannelMoments): Likewise.  Use __builtin_atan instead of
	atan.
