[sqlite] Remove obsolete reference version 3.8.7.4.

third_party/sqlite/sqlite-src-3080704/tool/speedtest8inst1.c

-/*
-** Performance test for SQLite.
-**
-** This program reads ASCII text from a file named on the command-line
-** and submits that text  to SQLite for evaluation.  A new database
-** is created at the beginning of the program.  All statements are
-** timed using the high-resolution timer built into Intel-class processors.
-**
-** To compile this program, first compile the SQLite library separately
-** will full optimizations.  For example:
-**
-**     gcc -c -O6 -DSQLITE_THREADSAFE=0 sqlite3.c
-**
-** Then link against this program.  But to do optimize this program
-** because that defeats the hi-res timer.
-**
-**     gcc speedtest8.c sqlite3.o -ldl -I../src
-**
-** Then run this program with a single argument which is the name of
-** a file containing SQL script that you want to test:
-**
-**     ./a.out test.db  test.sql
