Modulo-schedule loops in sparcv9a-mont.pl. Overall improvement factor

This is "informational" commit. Its mere purpose is to expose "modulo
...
factor" in inner loops.

As SPARCV9 CPU flavor is [expected to be] detected at run-time, we can

afford to relax SPARCV9/8+ compiler command line and produce "unversal"
binaries as we used to.

Switch 64-bit sparcv9 platforms from bn(64,64) to bn(64,32). This doesn't
...
have impact on performance, because amount of multiplications does not
increase with this switch, not on sparcv9 that is. On the contrary, it
actually improves performance, because it spares a load of instructions
used to chase carries. Not to mention that BN assembler modules can be
shared more freely between 32- and 64-bit builts.

Yet another "teaser" Montgomery multiply module, for UltraSPARC. It's not

integrated yet, but it's tested and benchmarked [see commentary section
for further details].
