Just some stylistic nits:

Please use full sentences starting with a capital letter, e.g.
New file.


>       * tree-vectorizer.h: new file.
>       * Makefile.in: new files tree-vectorizer.c,h

And close with a point:

Add new files tree-vectorizer.c,h.

Where does same apply to?  You might want to move it *after*
timevar.def if that comment applies.

If it's the same, you need to add (UNITS_PER_SIMD_WORD).
