    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 between shifts and bitfield inserts.

The second patch updates the Cortex-A57 scheduler now that we can differentiate
between shifts and bitfield inserts.  The Cortex-A57 Software Optimization Guide
indicates that BFM operations use the integer multi-cycle pipeline, while ARM
UXTB/H instructions use the Integer 1 or Integer 0 pipelines, so swap the bfm
and extend reservations.  This results in minor scheduling differences.

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.

	* config/aarch64/aarch64.c (cortexa57_vector_cost):
	Change vec_stmt_cost, vec_align_load_cost and vec_unalign_load_cost.
