Fix ChaCha assembly code on 32-bit HPUX itanium systems

Browse Source 
This fixes the reported crashes 32-bit HPUX systems due to
raw out and inp pointer values, and adds one nop instruction
on 64-bit systems, like it is done in other assembly modules
for those systems.

The fix was tested by @johnkohl-hcl see:
