cache page_size
...
page_size is used in every nearly every pointer calculation in os.rs,
and the Stack methods are called fairly often. It's definitely not worth
spilling registers for to call out to a libc function.
With this change, page_size becomes effectively free. It is cached in an
atomic usize, with relaxed ordering, so no actual atomic operations are
involved.
Benchmark:
```
test bench_page_size ... bench: 5 ns/iter (+/- 1)
test bench_page_size_cached ... bench: 0 ns/iter (+/- 0)
```

move Valgrind handling into Context
...
fix #3
This takes all Valgrind functionality private again.
Valgrind stack registrations are now associated with a Context, not with
a Stack. This makes sense, since it's only actually a stack when a
Context is running on it. Perhaps Valgrind will even be able to detect
early stack frees now.

We're now handling more of this ourselves, and leaving less to libstd.
Hopefully, we'll eventually break free of libstd, leaving a
highly-focused low-level library that retains all its conveniences in
freestanding environments.

Unlike valgrind_stack_register, this won't automatically swap
