1. qalloc() appears to have been a special routine written for the PPC440-based QCDOC supercomputer(s) from around 2005, its source does not seem to be readily available. So switch the #if 1 in the code to rely on standard malloc() by default.
2. Utility functions like get_num_procs, get_num_threads that were added to the "normally" used memory.c in the meantime were still missing here.

* Add automatic fixups for OSX/IOS cross-compilation

* Add OSX/IOS cross-compilation test to Travis CI

* Handle platforms that lack hwcap.h by falling back to ARMV8

* Fix PROLOGUE for OSX/IOS

* Add gcc7-generated assembly files for POWER8/9 isa/ica-min/max and POWER9 caxpy

To work around internal compiler errors encountered when compiling the original C source with gcc 4 and 5, and wrong code generated by gcc 8.3.0

* Use gcc-generated assembly instead of original C sources

to work around internal compiler errors encountered with gcc 4.8/5.4 and wrong code generation by gcc 8.3

* Use gcc-generated assembly instead of the original C source

to work around internal compiler errors encountered with gcc 4.8 and 5.4, and wrong code generation by gcc 8.3

* Add gcc7-generated assembler version of caxpy for power8

to work around wrong code generated by gcc 8.3

* Handle CONJ define for caxpyc

* Handle CONJ define for caxpyc

* Add gcc7-generated assembly cdot for POWER9

* Use prebuilt assembly for POWER9 cdot

created with gcc 7.3.1 to work around ICE in older gcc versions

* Exclude POWER9 from DYNAMIC_ARCH when gcc versions is lower than 6

* Update Makefile.system

* Use PROLOGUE macro to ensure correct function name for DYNAMIC_ARCH

* Disable POWER9 with old gcc versions

Provide more information on mmap/munmap failure

for #2207

Do not try ancient PGI hacks with recent versions of that compiler

should fix #2139

Fix errors in cpu affinity setup with glibc 2.6

for #2114

Misc. typo fixes in comments and documentation

fixes #2104

Found via `codespell -q 3 -w -L ith,als,dum,nd,amin,nto,wis,ba -S ./relapack,./kernel,./lapack-netlib`

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

Add CPUID data for Intel Denverton (as Nehalem)

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

Address warning in memory.c

Restore locking optimizations for OpenMP case

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

* Fix potential memory leak in cpu enumeration with glibc

An early return after a failed call to sched_getaffinity would leak the previously allocated cpu_set_t. Wrong calculation of the size argument in that call increased the likelyhood of that failure. Fixes #2003

* Restore dropped patches in the non-TLS branch of memory.c

As discovered in #2002, the reintroduction of the "original" non-TLS version of memory.c as an alternate branch had inadvertently used ba1f91f rather than a8002e2 , thereby dropping the commits for #1450, #1468, #1501, #1504 and #1520.

Move TLS key deletion to openblas_quit

fixes #1954 (as suggested by thrasibule in that issue)

to avoid a crash when OpenBLAS was loaded via dlopen and libc tries to clean up the leaked TLS after dlclose
Fixes #1720

cf. #1908

Add get_num_procs implementation for AIX

(and copy HAIKU implementation to the non-TLS version of the code as well)

Enable DYNAMIC_ARCH feature on ARM64. This patch uses the cpuid
feature in linux kernel to detect the core type at runtime
(https://www.kernel.org/doc/Documentation/arm64/cpu-feature-registers.txt).

If this feature is missing in kernel, then the user should use the
OPENBLAS_CORETYPE env variable to select the desired core type.

Remove the runtime setting of P, Q, R parameters for
targets ARMV8, THUNDERX2T99. Instead set them as constants
in param.h at compile time.
