Details: - Fixed bugs in trmv_l and trsv_u due to backwards iteration resulting in unaligned subpartitions. We were already going out of our way a bit to handle edge cases in the first iteration for blocked variants, and this was simply the unblocked-fused extension of that idea. - Fixed control tree handling in her/her2/syr/syr2 that was not taking into account how the choice of variant needed to be altered for upper-stored matrices (given that only lower-stored algorithms are explicitly implemented). - Added bli_determine_blocksize_dim_f(), bli_determine_blocksize_dim_b() macros to provide inlined versions of bli_determine_blocksize_[fb]() for use by unblocked-fused variants. - Integrated new blocksize_dim macros into gemv/hemv unf variants for consistency with that of the bugfix for trmv/trsv (both of which now use the same macros). - Modified bli_obj_vector_inc() so that 1 is returned if the object is a vector of length 1 (ie: 1 x 1). This fixes a bug whereby under certain conditions (e.g. dotv_opt_var1), an invalid increment was returned, which was invalid only because the code was expecting 1 (for purposes of performing contiguous vector loads) but got a value greater than 1 because the column stride of the object (e.g. rho) was inflated for alignment purposes (albeit unnecessarily since there is only one element in the object). - Replaced some old invocations of set0 with set0s. - Added alpha parameter to gemmtrsm ukernels for x86_64 and use accordingly. - Fixed increment bug in cleanup loop of gemm ukernel for x86_64. - Added safeguard to test modules so that testing a problem with a zero dimension does not result in a failure. - Tweaked handling of zero dimensions in level-2 and level-3 operations' internal back-ends to correctly handle cases where output operand still needs to be scaled (e.g. by beta, in the case of gemm with k = 0).
