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.
