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.

combine: Do not call simplify from inside change_zero_ext (PR78232)
When combine splits a three-insn combination into two instructions it
can reuse i2dest for the temporary result of the first new instruction.
However all information it has in reg_stat about that register will be
stale. This results in the simplify_gen_binary calls in change_zero_ext
using out-of-date information, which makes it think one of the ANDs
generated there always results in 0, and it doesn't get better from there.
This can also happen if a splitter in the MD uses nonzero_bits (for
example). I tried to make the splitting code in combine save and restore
the i2dest reg_stat info, but that causes one of the acats tests to fail.
This whole reg_stat thing needs an overhaul, and/or we shouldn't reuse
i2dest for unrelated purposes when splitting.
This patch changes change_zero_ext to do the expected simplifications
itself and not call simplify_gen_*.
