Fix thread races and infinite looping on systems with many cpus 
On systems with more than 64 cpus, blas_quickdivide will sometimes return zero which creates bogus workloads when used for the stride calculation. This then leads to threads spinning incessantly waiting for a status change that never happens, as seen in #1497.
This patch also fixes several data races that were found by helgrind and/or tsan while debugging the issue.

Hank Anderson e74462a3f5 Moved declarations to start of functions to satisfy MSVC C89 implementation. 2015-02-11 11:16:57 -06:00
Hank Anderson 056ba26755 Changed a number of inline calls to use __inline. 
MSVC doesn't inmplement C99, so can't use the inline keyword. __inline
appears to work in MSVC and GCC.

Zhang Xianyi 32d2ca3035 Refs #214, #221, #246. Fixed the getrf overflow bug on Windows. 
I used a smaller threshold since the stack size is 1MB on windows.

Zhang Xianyi 5d3312142a Refs #221 #246. Fixed the overflowing stack bug in mutlithreading BLAS3. 
When NUM_THREADS(MAX_CPU_NUNBERS) is very large ,e.g. 256.

typedef struct {
  volatile BLASLONG working[MAX_CPU_NUMBER][CACHE_LINE_SIZE * DIVIDE_RATE];
} job_t;

job_t          job[MAX_CPU_NUMBER];

The job array is equal 8MB.

Thus, We use malloc instead of stack allocation.
