4ddacd9921 Optimize SPARC T4 MONTMUL support. 
Improve RSA sing performance by 20-30% by:
- switching from floating-point to integer conditional moves;
- daisy-chaining sqr-sqr-sqr-sqr-sqr-mul sequences;
- using MONTMUL even during powers table setup;

7753a3a684 Add volatile qualifications to two blocks of inline asm to stop GCC from 
eliminating them as dead code.

Both volatile and "memory" are used because of some concern that the compiler
may still cache values across the asm block without it, and because this was
such a painful debugging session that I wanted to ensure that it's never
repeated.

3e181369dd C64x+ assembler pack. linux-c64xplus build is *not* tested nor can it be 
tested, because kernel is not in shape to handle it *yet*. The code is
committed mostly to stimulate the kernel development.

361512da0d This commit completes recent modular exponentiation optimizations on 
x86_64 platform. It targets specifically RSA1024 sign (using ideas
from http://eprint.iacr.org/2011/239) and adds more than 10% on most
platforms. Overall performance improvement relative to 1.0.0 is ~40%
in average, with best result of 54% on Westmere. Incidentally ~40%
is average improvement even for longer key lengths.
