Dear all,
this small patch fixes some small issues with the current FINAL
implementation, which is still disabled. Namely:
(a) class.c: TRANSFER has an optional size= argument; if one doesn't has
an actual-argument (which can be expr == NULL), it segfaults.
(b) class.c: SIZE needs to return

Basic-block vectorization removes scalar stmt calls (well, replaces them
with assignment from zero) even if the scalar result is used from
non-vectorized code (yes, that's a cost issue as well, I filed

This changes the vector of locations we track for each memory reference
from storing a pointer to a location aggregate to storing the aggregate
directly, avoiding an indirection and tons of small memory allocations.
This also touches the way we iterate over locations of refs - instead

This makes the linked list of dependent stmts a vector instead.

This patch is an attempt to warn about undefined behavior in simple loops
with known constant number of latch executions, which probably is the most
common case where gcc 4.8 started to turn finite loops involving undefined
