An incremental parsing system for programming tools

This change exposes a new `primary_state_ids` field on the `TSLanguage` struct, and populates it by tracking the first encountered state with a given `core_id`. (For posterity: the initial change just exposed `core_id` and deduplicated within `ts_analyze_query`). With this `primary_state_ids` field in place, the `ts_query__analyze_patterns` function only needs to populate its subgraphs with starting states that are _primary_, since non-primary states behave identically to primary ones. This leads to large savings across the board, since most states are not primary. |

tree-sitter
Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
