[patch] [4.2 projects] vectorize type conversions - 1/6 (updated versus r114433)

[Victor Kaplansky <VICTORK at il dot ibm dot com>]

This is updated version of "vectorize type conversions - 1/6" patch,
originally sent by Dorit in
http://gcc.gnu.org/ml//gcc-patches/2006-02/msg00940.html

-- Victor

This is a cleanup towards incorporating the new functionality:
Handling of aligned and unaligned loads can be largely unified, resulting
in a more readable code and avoids code duplication.

Bootstrapped with vectorization enabled and tested on the vectorizer
testcases on powerpc-linux.

ok for mainline?

thanks,
dorit
