AIX asm syntax changes needed for shared object creation

Fix for #2063

pool cleanup upon THREAD_DETACH which is needed when compiled with
USE_TLS=1.

Change 64-bit detection as explained in #2056

Use POSIX getenv on Cygwin

The Windows-native GetEnvironmentVariable cannot be relied on, as
Cygwin does not always copy environment variables set through Cygwin
to the Windows environment block, particularly after fork().

as suggested in #2022

add TARGET support for HiSilicon tsv110 CPUs

Add CPUID data for Intel Denverton (as Nehalem)

for #2048

Make TARGET=GENERIC compatible with DYNAMIC_ARCH=1

PowerMac 970 fixes

for issue #2048

without this, we see
../kernel/power/gemv_n.S:427:Parameter syntax error
and many more similar entries

that relates to this assembly command
dcbt 8, r24, r18

this change makes the DCBT_ARG = 0
and openblas builds through to completion on PowerMac 970
Tests pass

fixes:
gemm.c: In function 'sgemm_':
../common_param.h:981:18: error: 'SGEMM_DEFAULT_P' undeclared (first use in this function)
 #define SGEMM_P  SGEMM_DEFAULT_P
                  ^

Fix crash in sgemm SSE/nano kernel on x86_64

Fix bug #2047.

ctest.c : add __POWERPC__ for PowerMac

Do not compile in AVX512 check if AVX support is disabled

xgetbv is function depends on NO_AVX being undefined - we could change that too, but that combo is unlikely to work anyway

Fix module definition conflicts between LAPACK and ReLAPACK

Address warning in memory.c

for #2043

Correct range limiting in trmv_thread and re-enable TRMV multithreading

Improve handling of NO_STATIC and NO_SHARED

Restore locking optimizations for OpenMP case

add HiSilicon tsv110 CPUs  optimization branch

restore another accidentally dropped part of #1468 that was missed in #2004 to address performance regression reported in #1461
