Hello!

This [obvious] patch fixes off-by-one error in vectorizable_call() 
function. With this patch, x86_64 can be bootstrapped with -ftree-vectorize.

Patch was bootstrapped on x86_64-pc-linux-gnu (with -O2 -g 
-ftree-vectorize) and regression tested on vectorizer testcases. Patch 
was commited to SVN as obvious.
