[pseudo] Implement LRTable. This patch introduces a dense implementation of the LR parsing table, which is used by LR parsers. We build a SLR(1) parsing table from the LR(0) graph. Statistics of the LR parsing table on the C++ spec grammar: - number of states: 1449 - number of actions: 83069 - size of the table (bytes): 334928 Differential Revision: https://reviews.llvm.org/D118196 2022-02-11 21:09:15 +08:00			`_ := expr`
[pseudo] Fix an out-of-bound error in LRTable::find. The linear scan should not escape the TargetedStates range. Differential Revision: https://reviews.llvm.org/D120723 2022-03-01 22:49:21 +08:00			`expr := id`
