[Boost-build] -Op on MSVC-8.0

I'm using Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 
14.00.50215.44 for 80x86. I get this warning:

cl : Command line warning D9002 : ignoring unknown option '-Op'

I'm not sure if they removed or renamed this option, but either way I'd 
guess Boost-Build should be modified so it doesn't use it by default.

I also notice Boost-Build passes /Zm800 every time it launches MSVC, which I 
think could cause problems if someone needs to set this option to another 
value. Why not use the compiler default for stuff that doesn't map to the 
portable built-in Boost-Build <features>? After all, if the users need to 
pass global options to all their files, they can do this in jamroot, no?

Thanks,
Emil
