Details: - Fixed a bug that would cause configurations to inadvertantly define their integers to be 32 bits when those environments actually call for 64-bit integers. While either BLIS_ARCH_64 or BLIS_ARCH_32 is defined in bli_system.h (based on whether preprocessor macros such as __x86_64 or __aarch64__ are defined by the environment), bli_system.h was being #included *after* bli_config_macro_defs.h, in which the BLIS_ARCH_64 macro was used to choose an integer type size in the event that BLIS_INT_TYPE_SIZE was not already defined by configure via bli_config.h. And due to the structure of the cpp code in that file, the 32-bit integer case was being chosen. Thanks to Francisco Igual and Devangi Parikh for their help in isolating this bug. - Moved the #include of hbwmalloc.h and related preprocessor code to bli_kernel_macro_defs.h to facilitate the reshuffling of the #include for bli_system.h in blis.h.
