Overview
Comment:Enhance the Lemon parser generator so that it creates a faster parser at the cost of slightly larger parser tables. Add the ability to measure coverage of the generated state machine when compiling with the -DYYCONVERGE option. In SQLite, add the SQLITE_TESTCTRL_PARSER_COVERAGE test-control to query the new parser coverage feature.

The output of sqlite3_trace() now shows each command of a trigger as it is evaluated. This feature involved major changes to the parser, such as removing the ExprSpan object and replacing it with a new mechanism for capturing the original SQL text of phrases in the input SQL.
