9d41fa4489 implement IN patterns for non-conditional SELECT queries 
Extracts the core logic of IN from the conditional version, and uses the
conditional metadata to determine the jump. Then Uses the AddImm
operator we just added to force the integer conversion at the end (like
SQLite does).

022f679fab chore: make every CREATE TABLE stmt in entire repo have 1 space after tbl name 
`BTreeTable::to_sql` makes us incompatible with SQLite by losing e.g. the original whitespace provided during the CREATE TABLE command.

For now let's fix our tests by regex-replacing every CREATE TABLE in
the entire repo to have exactly 1 space after the table name in the
CREATE TABLE statement.

cbdd5c5fc7 improve handling of double quotes 
I ended up hitting #1974 today and wanted to fix it. I worked with
Claude to generate a more comprehensive set of queries that could fail
aside from just the insert query described in the issue. He got most of
them right - lots of cases were indeed failing. The ones that were
gibberish, he told me I was absolutely right for pointing out they were
bad.

But alas. With the test cases generated, we can work on fixing it. The
place where the assertion was hit, all we need to do there is return
true (but we assert that this is indeed a string literal, it shouldn't
be anything else at this point).

There are then just a couple of places where we need to make sure we
handle double quotes correctly. We already tested for single quotes in a
couple of places, but never for double quotes.

There is one funny corner case where you can just select "col" from tbl,
and if there is no column "col" on the table, that is treated as a
string literal. We handle that too.

Fixes #1974

eb00226cfe Add support for CASE expressions. 
There's two forms of case:
  CASE (WHEN [bool expr] THEN [value])+ (ELSE [value])? END
which checks a series of boolean conditions, and:
  CASE expr (WHEN [expr] THEN [value})+ (ELSE [value])? END
Which checks a series of equality conditions.

This implements support for both. Note that the ELSE is optional, and
will be equivalent to `ELSE null` if not specified.

sqlite3 gives the implementation as:

sqlite> explain select case a WHEN a THEN b WHEN c THEN d ELSE 0 END from casetest;

And then as there's nowhere to annotate this new support in COMPAT.md, I
added a corresponding heading for SELECT expressions and what is/isn't
supported.
