[whatwg] "html" start tag token in the root element phase

[Henri Sivonen]

If the spec dealt with the "html" start tag token directly in the  
root element phase, the parse error in the main phase wouldn't need  
to be conditional. (Implementations that experience a perf benefit  
from not mutating the attributes of a node probably want to hoist the  
"html" node creation to the root element phase for perf reasons, too.)
