(Note that I misread the press release, and that only the 
C++ compiler is in the future, that being said, *If* the 
above was true...)

Linux is written in C.

C requires a C compiler.

How does one compile Linux for the new instruction 
set and architecture without a C compiler?

(Note: there are subtleties that the above oversimplified
description ignores.)

f(n) = (n-1)*n/2

f(64) = 2016

It's most likely not implemented as P2P, didn't read the specs but
that's a high propability.

Turn on the thread-number display in your task manager process view on 
Winwoes, and tell me that column contains mostly 1. Not true.

But those threads are sleeping 99.99% of the time. That's the reality
