A couple of the data members in the Gogo class were not
being initialized properly. This was causing "uninitialized value"
errors during Valgrind memcheck runs. This patch insures that
all of the fields receive an initial value.

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.

* config/aarch64/aarch64.c (generic_tunings): Add AES fusion.

compiler: check backend alignment for memequalNN functions
The code was assuming the usual required alignment for the memequalNN
functions (16 bits for int16, 32 for int32, etc.). However, on m68k
the required alignment of int32 is only 16 bits. Assuming the
memequalNN alignment caused the compiler to incorrectly decide that
int32 required a specially generated function rather than calling
memequal32. This then crashed if the type descriptor were generated
after type-specific functions had been written.
Fixes GCC PR 80128.
