The SD/SFmode move pattern used a wrong mnemonic for vector load
element.
On the vector load element instruction was an operand missing.

The boundary argument of the vec_load_bndry builtin needs to be
rewritten.  At that point it must be constant already.  The current
diagnostics in s390_expand_builtins is too late for this.  The patch
adds an additional check for that builtin which will be triggered
already during preprocessing.

In  https://gcc.gnu.org/ml/gcc-patches/2015-11/msg01639.html James determined
the best value for AArch64 code generation.  Although this setting is used when
explicitly targeting Cortex cores, it is not otherwise used.  This means by
default GCC will not use (F)CSEL in many common cases. 

Change the generic_branch_cost to be the same as cortexa57_branch_cost so that
all supported cores benefit from CSEL.  This is generally faster and smaller.
On one benchmark the new setting fixes a regression since GCC6 and improves
performance by 49%.

	* config/aarch64/aarch64.c (generic_branch_cost):
	Copy cortexa57_branch_cost.

Many supported cores implement fusion of AES instructions.  When fusion
happens it can give a significant performance gain.  If not, scheduling
fusion candidates next to each other has almost no effect on performance.
Due to the high benefit/low cost it makes sense to enable AES fusion with
-mcpu=generic so that cores that support it always benefit.
