dfb316d432 Changes to delay freeing buffers associated with vdbe memory cells until either sqlite3_finalize() or sqlite3_release_memory() is called. (CVS 4922)

e14006d0de Modify the {quote: IdxDelete} opcode so that it takes an array of registers rather 
than a record formed using {quote: MakeRecord.}  This avoids a needless packing
and unpacking of the record to be deleted. (CVS 4916)

1e968a0cbf Removed the direct btree tests - part of the ongoing effort to test by 
calling only public interfaces.  Modify the sqlite3VdbeRecordCompare
interface to used a pre-parsed second key - resulting in a 13%
performance improvement on speed1p.test. (CVS 4911)

d4e70ebd6f Begin setting a foundation on which to convert the VM from a stack-based

this check-in.  This change merely begins adding infrastructure to support
a register-based architecture. (CVS 4652)
