[PATCH] Make vectorizer dumps more comparable

- Subject: [PATCH] Make vectorizer dumps more comparable
This avoids the file/location clutter in front of each line
in the vectorizer dump. While this is useful for people
requesting -fvectorizer-verbose=N in dump files this makes
you unable to compare dumps for testcases on a branch and trunk.
It also makes lines excessively long because the testsuite
filename paths are so long. Very annoying.
(I'd argue also that -fvectorizer-verbose=N dumps to the dump
file if available and not always to stderr is bogus, but well ...)
This patch has made my life a lot easier debugging the data dependence
stuff.
Bootstrapped and tested on x86_64-unknown-linux-gnu, installed on trunk.
Richard.

file and location clutter when dumping to dump files.
