Reduce method names converted to upper case via uppercaseKnownHTTPMethod()

Reduce method names converted to upper case via uppercaseKnownHTTPMethod()

Per http://xhr.spec.whatwg.org/#dom-xmlhttprequest-open, as of 5/4/2014, only the DELETE, GET, HEAD,
OPTIONS, POST and PUT methods ought to be converted to upper case. Correcting this behaviour passes
two additional WPT suites.

Patch adjusts XMLHttpRequest to convert only DELETE, GET, HEAD, OPTIONS, POST
and PUT requests to uppercase, leaving other requests as-is, in accordance with
the current state of the xhr spec by annevk. It passes an extra couple of WPT
suites, in addition to the test cases included in the patch.

Thanks for the patch, but I think abarth is likely a better reviewer than me
(XHR is not my specialty).

Also, I don't see your email address in
http://src.chromium.org/viewvc/chrome/trunk/src/AUTHORS. Looking at the review
on your last commit (with tkent, https://codereview.chromium.org/132483006), it
sounds like you have signed the CLA but simply haven't added yourself to the
AUTHORS file. Please do so, as it makes it easier for reviewers to handle your
patches.

Oh sorry, you were the suggested owner gclient gave me, but most of the file
seems to predate the blink fork anyways, so I wasn't sure who would be a good
reviewer.

I will try to get myself added to authors
