Switch expressions spec

[Alex Buckley]

For clarity, we have renamed the January 2019 version from:

http://cr.openjdk.java.net/~gbierman/switch-expressions-old.html

to:

http://cr.openjdk.java.net/~gbierman/switch-expressions-2019-01.html

The CSR for switch expressions (JDK-8207241) has the spec as an 
attachment, but also links to an online version for reader convenience. 
Originally it linked to `switch-expressions.html`, but that is a living 
document and hence unsuitable for a CSR, so now it links to 
`switch-expressions-2019-01.html`.

I have also taken the opportunity to reorder chapter 15 slightly, so switch expressions are now section 15.28 and constant expressions are now section 15.29 (the last section in the chapter).
