Fix handling of unknown sizes in rtx_addr_can_trap_p

If the size passed in to rtx_addr_can_trap_p was zero, the frame
handling would get the size from the mode instead.  However, this
too can be zero if the mode is BLKmode, i.e. if we have a BLKmode
memory reference with no MEM_SIZE (which should be rare these days).
This meant that the conditions for a 4-byte access at offset X were
stricter than those for an access of unknown size at offset X.

This patch checks whether the size is still zero, as the
SYMBOL_REF handling does.

Fix nb_iterations_estimate calculation in tree-vect-loop.c

vect_transform_loop has to reduce three iteration counts by
the vectorisation factor: nb_iterations_upper_bound,
nb_iterations_likely_upper_bound and nb_iterations_estimate.
All three are latch execution counts rather than loop body
execution counts.  The calculations were taking that into
account for the first two, but not for nb_iterations_estimate.

This patch updates the way the calculations are done to fix
this and to add a bit more commentary about what is going on.

This isn't true for the avr - shorts and ints are of the same size, and

Use simplify_gen_binary in canon_rtx

Add a load_extend_op wrapper

LOAD_EXTEND_OP only applies to scalar integer modes that are narrower
than a word.  However, callers weren't consistent about which of these
checks they made beforehand, and also weren't consistent about whether
"smaller" was based on (bit)size or precision (IMO it's the latter).
This patch adds a wrapper to try to make the macro easier to use.

LOAD_EXTEND_OP is often used to disable transformations that aren't
beneficial when extends from memory are free, so being stricter about
the check accidentally exposed more optimisation opportunities.

"SUBREG_BYTE (...) == 0" and subreg_lowpart_p are implied by

Fix simplify_shift_const_1 handling of vector shifts

simplify_shift_const_1 handles both shifts of scalars by scalars
and shifts of vectors by scalars.  For vectors this means that
each element is shifted by the same amount.

However:

(a) the two cases weren't always distinguished, so we'd try
        things for vectors that only made sense for scalars.

(b) a lot of the range and bitcount checks were based on the
        bitsize or precision of the full shifted operand, rather
        than the mode of each element.

Fixing (b) accidentally exposed more optimisation opportunities,

Move misplaced assignment in num_sign_bit_copies1

The old assignment to bitwidth was before we handled VOIDmode with:

      if (mode == VOIDmode)

so when VOIDmode was specified we would always use:

runtime: don't crash if signal handler info argument is nil

    Apparently on Solaris 10 a SA_SIGINFO signal handler can be invoked with
    a nil info argument.  I would not have believed it but I've now seen it
    happen, and the sigaction man page actually says "If the second argument
    is not equal to NULL, it points to a siginfo_t structure...."  So, if
    that happens, don't crash.

The second patch updates the Cortex-A57 scheduler now that we can differentiate

insert.  Add a new bfx attribute for these instructions so that they can be

The existing vector costs stop some beneficial vectorization.

The existing vector costs stop some beneficial vectorization.  This is mostly
due to vector statement cost being set to 3 as well as vector loads having a
higher cost than scalar loads.  This means that even when we vectorize 4x, it
is possible that the cost of a vectorized loop is similar to the scalar
version, and we fail to vectorize.

Using a cost of 3 for a vector operation suggests they are 3 times as
expensive as scalar operations.  Since most vector operations have a
similar throughput as scalar operations, this is not correct.

Using slightly lower values for these heuristics now allows this loop
and many others to be vectorized.  On a proprietary benchmark the gain
from vectorizing this loop is around 15-30% which shows vectorizing it is
indeed beneficial.
