1c6ad5f7e4 Rename ubiquitous_tokens -> extra_tokens in compiler API 
They were already called this in the runtime code.
'Extra' is just easier to say.

c495076adb Record in parse table which actions can hide splits 
Suppose a parse state S has multiple actions for a terminal lookahead symbol A.
Then during incremental parsing, while in state S, the parser should not
reuse a non-terminal lookahead B where FIRST(B) contains A, because reusing B
might prematurely discard one of the possible actions that a batch parser
would have attempted in state S, upon seeing A as a lookahead.

ad619d95f6 Add 'extra' field to symbol metadata 
This stores whether a symbol is only ever used as a ubiquitous token. This will
allow ubiquitous nodes to be reused more effectively: if they are always
ubiquitous, then they can be reused immediately, and otherwise, they must be
broken down in case they need to be used structurally.
