Bug #57228	No ICC-compiled tarball for MySQL 5.1.51

Description:
All MySQL versions up to 5.1.50 had the binaries also compiled using the Intel Compiler (ICC), which, according to MySQL, offers 20% performance increase when ran on Intel CPUs. However, MySQL 5.1.51 is the first release not to offer ICC-compiled binaries as an option. I wonder if the support for ICC was dropped or you guys simply forgot to compile and put the file online. Please advice.

How to repeat:
Look at http://dev.mysql.com/downloads/mysql/5.1.html#downloads, select Linux - Generic and try locating a file with icc on its name. For this particular version it should be called mysql-5.1.51-linux-x86_64-icc-glibc23.tar.gz, but this file is not available.

Suggested fix:
Please compile MySQL 5.1.51 with ICC and put it online. Thanks.

As far as I know we do not distribute binaries built with ICC any more (for whatever reasons). But as this is not explained at http://dev.mysql.com/doc/refman/5.1/en/news-5-1-51.html I think we have a valid documentation request here.

http://dev.mysql.com/doc/refman/5.1/en/news-5-1-50.html says:

"
This is the final release of MySQL 5.1 for which MySQL binary distributions built with the icc compiler will be offered (with the exception of specific IA64 RPM packages for RHEL and SLES, because icc is the recommended compiler for that platform). Previously obtained performance benefits compared to other available compilers have diminished, and recent versions have begun to present build and runtime problems.
"

This note was not added until after the 5.1.50 release went out, so it was added too late to be part of the release announcement.
