6e42757644 The output of sqlite3_trace() now shows each command of a trigger as it is

removing the ExprSpan object and replacing it with a new mechanism for
capturing the original SQL text of phrases in the input SQL.

7038a991b0 Change the coverage measurement logic in the lemon-generated parser so that
it only checks for coverage of state/lookahead pairs that are valid syntax.
It turns out that some states are unreachable if the lookahead is not valid
syntax, because the states are only reachable through a shift following a
reduce, and the reduce does not happen if the lookahead is a syntax error.

3a9d6c7156 Enhance LEMON so that it generates the action table in such a way that no

token is valid.  This makes the lookahead table slightly larger (about 120
bytes) but helps the parser to run faster.
