facf47a891 Use the padding word in the Mem object as temporary storage for 
serial_type value in OP_Record, and thus avoid a redundant computation of
the serial_type for each column.

6cf4a7dfa6 Remove the OPFLAG_CLEARCACHE flag from OP_Column. In its place, change the 
P3 parameter of OP_SorterData to be the index of the pseudo-table cursor whose
record header cache is to be cleared.  This gives a small size reduction
and performance increase.

b53a5a9e50 Remove the VdbeCursor.lastRowid cache of the current rowid, since maintaining 
the correct cache value uses more CPU cycles than just recomputing the rowid
on the occasions when it is actually needed.  Replace it with the
VdbeCursor.aOffset field which used to be computed from VdbeCursor.aType
when needed. Saves 100 bytes of code space and runs 0.2% faster.

d6176c4131 Simplification to the insertCell() routine in btree.c, resulting in a 
performance boost and a very small size decrease.  It turns out that the
extra work involved in sometimes avoiding an memcpy() of the first four bytes
of a record takes more time than just unconditionally copying those
four bytes.
