4b04afac5e Control lexer's error-mode via explicit boolean argument 
Previously, the lexer would operate in error-mode (ignoring any garbage input
until it found a valid token) if it was invoked in the 'error' state. Now that
the error state is deduped with other lexical states, the lexer might be invoked
in that state even when error-mode is not intended. This adds a third argument
to `ts_lex` that explicitly sets the error-mode.

This bug was unlikely to occur in any real grammars, but it caused the
node-tree-sitter-compiler test suite to fail for some grammars with only one
rule.

939476c947 When removing duplicate lex states, update the error state too 
Now, instead of being stored as a separate field on the parse table, the error
state is just the first state in the states vector.

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.
