Details: - Modified all control tree node definitions to include a new field of type func_t*, which is similar to a blksz_t except that it contains one function pointer (each typed simply as void*) for each datatype. We use the func_t* to embed pointers to the micro-kernels to use for the leaf-level nodes of each control tree. This change is a natural extension of control trees and will allow more flexibility in the future. - Modified all macro-kernel wrappers to obtain the micro-kernel pointers from the incomming (previously ignored) control tree node and then pass the queried pointer into the datatype-specific macro-kernel code, which then casts the pointer to the appropriate type (new typedefs residing in bli_kernel_type_defs.h) and then uses the pointer to call the micro- kernel. Thus, the micro-kernel function is no longer "hard-coded" (that is, determined when the datatype-specific macro-kernel functions are instantiated by the C preprocessor). - Added macros to bli_kernel_macro_defs.h that build datatype-specific base names if they do not exist already, and then uses those to build datatype-specific micro-kernel function names. This will allow developers extra flexibility if they wanted to, for example, name each of their datatype-specific micro-kernels differently (e.g. double real might be named bli_dgemm_opt_4x4() while double complex might be named bli_zgemm_opt_2x2()). - Inserted appropriate code into _cntl_init() functions that allocates and initializes a func_t object for the corresponding micro-kernels. The gemm ukernel func_t object is created once, in bli_gemm_cntl_init(), and then reused via extern wherever possible.
