blis/frame/include/level0/bli_xpbys_mxn.h
Field G. Van Zee 3eef698711 Declare/define static functions via BLIS_INLINE. 
Details:
- Updated all static function definitions to use the cpp macro
  BLIS_INLINE instead of the static keyword. This allows blis.h to
  use a different keyword (inline) to define these functions when
  compiling with C++, which might otherwise trigger "defined but
  not used" warning messages. Thanks to Giorgos Margaritis for
  reporting this issue and Devin Matthews for suggesting the fix.
- Updated the following files, which are used by configure's
  hardware auto-detection facility, to unconditionally #define
  BLIS_INLINE to the static keyword (since we know BLIS will be
  compiled with C, not C++):
    build/detect/config/config_detect.c
    frame/base/bli_arch.c
    frame/base/bli_cpuid.c
- CREDITS file update.
