This patch makes use of new POWER10 vector pair instructions for
loads and stores. Tested in simulator and no new failures.

For the first iteration, it is better to use xvf*ger instead of xvf*gerpp
builtins which helps to avoid setting accumulators to zero. This helps
to reduce few instructions.

Making use of new vector pair POWER10 instructions in dgemv_n and dgemv_t.
Also adding a new block 4x128 to make use of Matrix-Multiply Assist (MMA)
feature introduced in POWER ISA v3.1.  Tested on simulator and there
are no new test failures.

As gcc defaults to -malign-power, removing that option. Also
adding -fno-integrated-as to use GNU assembler for powerpc
assembly optimization files. Fixed other compilation errors
reported in dgemv_t.c file.

There is a recent compiler change in __builtin_mma_disassemble_acc() which
affects the order of storing result in POWER10. Also removing new LDFLAG
-mno-power10-stub as it is handled by linker automatically.

WIP Further fixes for 32bit POWER8

Fix alignment errors in the power8 saxpy kernel

This patch introduces new optimized version of SHGEMM kernel
using power10 Matrix-Multiply Assist (MMA) feature introduced in
POWER ISA v3.1. This patch makes use of new POWER10 compute instructions
for matrix multiplication operation.

Tested on simulator and there are no new test failures.

This patch introduces new optimized version of ZGEMM kernel
using power10 Matrix-Multiply Assist (MMA) feature introduced in
POWER ISA v3.1. This patch makes use of new POWER10 compute instructions
for matrix multiplication operation.

Tested on simulator and there are no new test failures.
Cycles count reduced by 30-50%  compared to POWER9 version depending on
M/N/K sizes.

This is the initial patch to support build infrastructure
for POWER10 architecture.

in response to test failures seen in #2628 and BLAS-Tester

This patch removes extra space in the sgemmotcopy filename
thereby allowing it to create entry in kernel/Makefile
created by cmake.

for #2299

Setting DYNAMIC_ARCH=1 on POWER9 does not build POWER9 files due to some
compiler version checks.  This patch fixes some of the macros that are used
to check compiler version.  On fixing those checks, there are some new make
failures related to icamin, icamax, isamin, isamax and caxpy files on POWER9.
This patch fixes those failures as well.

the fallbacks from Makefile.L1 assume a combined source for absolute value and non-absolute (with ifdef USE_ABS) but here we have separate implementations

to fix utest failure in new ismin test -  Makefile.L1 defaults look wrong

Changes to build on AIX in POWER8 mode

Fix precompiled kernels on POWER9 and make their use conditional on (old) gcc version

We were corrupting r2 because the local entry wasn't being
setup correctly.
