[Patch ARM] Fix Neon vshll disassembly.

[Ramana Radhakrishnan]

Hi,

	The subject line says it all. The tests and the input were just broken, 
vshll.u8 writes to a Q register reading from a D register and not the 
other way around ! Looks like a copy paste error when the support went in.

Tested arm-none-eabi cross with gas. No regressions.

Ok for trunk and release branches ?

regards
Ramana
