Added count of my_sync calls (to SHOW STATUS)

tmp_table_size can now be set to 0 (to disable in memory internal temp tables)
Improved speed for internal Maria temp tables:
- Don't use packed keys, except with long text fields.
- Don't copy key all accessed pages during key search.
Some new benchmark tests to sql-bench (for group by)

BUILD/compile-pentium64-gcov:
  Update script to use same pentium_config flags as other tests
BUILD/compile-pentium64-gprof:
  Update script to use same pentium_config flags as other tests
include/my_sys.h:
  Added count of my_sync calls
mysql-test/r/variables.result:
  tmp_table_size can now be set to 0
sql-bench/test-select.sh:
  Added some new test for GROUP BY on a not key field and group by with different order by
sql/mysqld.cc:
  Added count of my_sync calls
  tmp_table_size can now be set to 0 (to disable in memory internal temp tables)
sql/sql_select.cc:
  If tmp_table_size is 0, don't use in memory temp tables (good for benchmarking MyISAM/Maria temp tables)
  Don't pack keys for Maria tables;  The 8K page size makes packed keys too slow for temp tables.
storage/maria/ma_key_recover.h:
  Moved definition to maria_def.h
storage/maria/ma_page.c:
  Moved code used to simplify comparing of identical Maria tables to own function (page_cleanup())
  Fixed that one can read a page with a read lock.
storage/maria/ma_rkey.c:
  For not exact key reads, cache the page where we found key (to speed up future read-next/read-prev calls)
storage/maria/ma_search.c:
  Moved code to cache last key page to separate function.
  Instead of copying pages, only get a link to the page. This notable speeds up key searches on bigger tables.
storage/maria/ma_write.c:
  Added comment
storage/maria/maria_def.h:
  Moved page_cleanup() to separate function.

Bug#23062 (GCOV build: helper scripts missing in the BUILD directory)

This patch provides compile helper scripts only,
no server logic is affected.

Before this patch, GCOV and GPROF build scripts were only provided for
pentium platforms.

With this patch, pentium, pentium64 and amd64 platforms have associated
helper build scripts.

The GCOV and GPROF specific compilation flags are set once in SETUP.sh,
to avoid code duplication.


BUILD/SETUP.sh:
  Moved GCOV and GPROF flags to compile-pentium-{gcov,gprof) to SETUP.sh
BUILD/compile-pentium-gcov:
  Moved GCOV and GPROF flags to compile-pentium-{gcov,gprof) to SETUP.sh
BUILD/compile-pentium-gprof:
  Moved GCOV and GPROF flags to compile-pentium-{gcov,gprof) to SETUP.sh
BUILD/compile-amd64-gcov:
  Added helper scripts for GCOV and GPROF builds.
BUILD/compile-amd64-gprof:
  Added helper scripts for GCOV and GPROF builds.
BUILD/compile-pentium64-gcov:
  Added helper scripts for GCOV and GPROF builds.
BUILD/compile-pentium64-gprof:
  Added helper scripts for GCOV and GPROF builds.
