In OpenMP threading, preallocate the thread buffer instead of allocating the buffer every time. This patch improved the performance slightly.

Instead of using thread 0 buffer, each thread uses its own sb buffer.
Thus, it can avoid overflowing thread 0 buffer.

cblas: typedef enums for improved compatibility with Intel MKL.
...
Netlib style:
enum CBLAS_XYZ {X=1, Y=2, Z=3};
Intel MKL style:
typedef enum {X=1, Y=2, Z=3} CBLAS_XYZ;
With this hybrid style, code written in the latter form won't need any
modifications to be built with OpenBLAS. This change should not affect existing
code, although a warning may be emitted for C code which does the following
(does not occur with C++):
typedef enum CBLAS_XYZ CBLAS_XYZ;
warning: redefinition of typedef 'CBLAS_XYZ' [-pedantic]

if we have 64 bit pointers we can't have a 32 bit cpu, so fall back to
the 64bit cpu fallback (prescott)
E.g. the cpu detection fails in amd qemu64 emulation (family 6 model 2)
causing it to use the uninitialized gotoblas_ATHLON
