The function might return an offset to the main table or to an index,
depending on whether the column X would be loaded from the main table or
from the index.

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.

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.

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.

range check is needed on the lookahead table to verify that the next input
token is valid. This makes the lookahead table slightly larger (about 120
bytes) but helps the parser to run faster.

so that reduce actions occur last. This means that the most common case
(reduce actions) can be recognized with a single comparison operation, thus
speeding up the main parser loop, slightly.
