powerpc: Optimized SGEMM/DGEMM/CGEMM for POWER10
This patch introduces new optimized version of SGEMM, CGEMM and DGEMM
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.
MMA GCC patch for reference:

make GCC version detection OS-independent
Previous design put GCC version detection inside of OSNAME 'WINNT'.
However, such detections are required for 'Linux' and possibly other
OS'es as well. For example, there is usage of the GCC versions
in Makefile.arm64. When compiling on Linux machine, in the previous
design, Markfile.arm64 will not know the correct GCC version.
The fix is to move GCC version detection into common part, not
wrapped by anything.
