When constructing an :? or fold expression that requires a third

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
paradoxical_subreg_p, so the patch also removes some redundant tests.
The patch doesn't change reload, since different checks could have
unforeseen consequences.

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)
mode = GET_MODE (x);
so when VOIDmode was specified we would always use:
if (bitwidth < GET_MODE_PRECISION (GET_MODE (x)))
{
num0 = cached_num_sign_bit_copies (x, GET_MODE (x),
known_x, known_mode, known_ret);
return MAX (1,
num0 - (int) (GET_MODE_PRECISION (GET_MODE (x)) - bitwidth));

pessimistic result).

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.
Also fix another case where we want to make sure that &T{} does not
allocate.

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.
