1d8b85bed1 Have the crash-test infrastructure code in test6.c read and write the 512-byte block containing the pending-byte lock as normal. Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed. And not reading/writing this part of the file causes problems for multiplexor tests.

2dc0648a80 Do not run the tool/vdbe-compress.tcl script that generates the 
vdbeExecUnion object that reduces the size of the sqlite3VdbeExec()
stack frame unless the SQLITE_SMALL_STACK compile-time option is
specified as on of the OPTS in the makefile.  The vdbeExecUnion object
gets in the way of C-compiler optimizer and results in slightly slower code.
