208c7e7ca5 Use acq/rel semantics to pass flags/pointers in getrf_parallel. 
The current implementation has locks, but the locks each only
have a critical section of one variable so atomic reads/writes
with barriers can be used to achieve the same behavior.

Like the previous patch, pthread_mutex_lock isn't fair, so in a
tight loop the previous thread that has the lock can keep it
starving another thread, even if that thread is about to write
the data that will stop the current thread from spinning.

On a 64c Arm system this improves performance by 20x on sgesv.goto.

19f3a4091c Make rpcc() on arm64 get closer to what x86 returns 
The Arm implementation of rpcc() uses the architected timer
which is defined by the SBSA to be between 10-400MHz. These numbers
are much smaller than the cycle counter frequency used by x86. Make
the numbers closer by shifting the cycle counter up by the number of
leading zeros in the cntfrq_el0 register which gets us closer to a
noraml cpu clock cycle range.

a66f4d80c8 Apply MinGW AVX512 compilation fix to fortran options as well 
original issue was #1708, I see now that the same problem affects gfortran compilation. The underlying issue is said to be fixed (but not yet released) on all branches of gcc as of a few days ago but it will certainly take time to reach mingw/msys.
