bb53ecb1db Enhancements to the code generator for the IN operator that result in much 
faster queries in some cases, for example when the RHS of the IN operator
changes for each row of a large table scan.

9296c18a50 Change the hex literal processing so that only the SQL parser understands 
hex literals.  Casting and coercing string literals into numeric values does
not understand hexadecimal integers.  This preserves backwards compatibility.
Also:  Throw an error on any hex literal that is too big to fit into 64 bits.

a45fdc7b1e The optimization of check-in [b67a6e33f2] does not work (it generates 
incorrect VDBE code) if an OR term is AND-ed with a constant expression.

get added back in.

a1f7c0a21c Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter 
database corruption, they will set the UnpackedRecord.isCorrupt field and
return 0.  The sqlite3BtreeMovetoUnpacked() routine detects this and returns
SQLITE_CORRUPT, causing the corruption to be reported back to the top-level.

fbb24d1092 The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is 
incorrect, as demonstrated by the in4-5.1 test case in this check-in.
The "COLLATE binary" that was being added to the RHS of IN was overriding
the implicit collating sequence of the LHS.  This change defines the EP_Generic
expression node property that blocks all affinity or collating sequence
information in the expression subtree and adds that property to the expression
taken from RHS of the IN operator.
