The one design choice here was whether to expose the pointee directly through the Mirror
My choice was against that. Instead, we present UnsafePointer as UnsafePointer(0x123) and the child we expose is the 0x123 numeric pointer value
The other option, of course, would be to present it as UnsafePointer(reflect(memory)) - but that seems risky to do by default
UnsafePointers are allowed to be in, guess what, unsafe states, and the stakes of having playgrounds try and dereference at all times are quite too high.
If the user really wants to reflect the pointee reflect(pointer.memory) will do it for them - and then any crashes will be theirs to enjoy.
Of course, I am very open to arguments as to why reflect(memory) would be a better choice.

- Follow LLVM conventions for emacs mode specification
- Use local variables suffix to make the output read-only (at least on
Emacs)
- But drop the admonitions not to edit the generated files;
line-directive mostly takes care of that problem now.

As before, there may be more things marked @public than we actually want
public. Judicious use of the frontend option -disable-access-control may
help reduce the public surface area of the stdlib.

Give UnsafePointer versions of CMutablePointer._setIfNonNil and _withBridgeObject/Value. Also provide a version of 'withUnsafePointer' as a staging aid so that UnsafePointer can be used in place of CMutablePointer.

Keep calm: remember that the standard library has many more public exports
than the average target, and that this contains ALL of them at once.
I also deliberately tried to tag nearly every top-level decl, even if that
was just to explicitly mark things @internal, to make sure I didn't miss
something.
This does export more than we might want to, mostly for protocol conformance
reasons, along with our simple-but-limiting typealias rule. I tried to also
mark things private where possible, but it's really going to be up to the
standard library owners to get this right. This is also only validated
against top-level access control; I haven't fully tested against member-level
access control yet, and none of our semantic restrictions are in place.
Along the way I also noticed bits of stdlib cruft; to keep this patch
understandable, I didn't change any of them.

This is motivated by <rdar://problem/17051606>.
This ends up renaming variables as well, which seems right for
consistency since we use "predicate" as variable name.
