Field G. Van Zee 2d9c667f3c Fixed x86_64 kernel bugs and other minor issues.
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).
