69567687b0 bn/asm/x86_64-mont5.pl: fix valgrind error. 
bn_get_bits5 was overstepping array boundary by 1 byte. It was exclusively
read overstep and data could not have been used. The only potential problem
would be if array happens to end on the very edge of last accesible page.

579734ced6 bn/asm/vis3-mont.pl: fix intermittent EC failures on SPARC T3. 
BLKINIT optimization worked on T4, but for some reason appears "too
aggressive" for T3 triggering intermiitent EC failures. It's not clear
why only EC is affected...

c1669e1c20 Remove inconsistency in ARM support. 
This facilitates "universal" builds, ones that target multiple
architectures, e.g. ARMv5 through ARMv7. See commentary in
Configure for details.

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.
