26c5cf495c Fixed bug in skx subconfig related to bdd46f9.
Details:
- Fixed code in the skx subconfiguration that became a bug after
  committing bdd46f9. Specifically, the bli_cntx_init_skx() function
  was overwriting default blocksizes for the scomplex and dcomplex
  microkernels despite the fact that only single and double real
  microkernels were being registered. This was not a problem prior to
  bdd46f9 since all microkernels used dynamically-queried (at runtime)
  register blocksizes for loop bounds. However, post-bdd46f9, this
  became a bug because the reference ukernels for scomplex and dcomplex
  were written with their register blocksizes hard-coded as constant
  loop bounds, which conflicted the the erroneous scomplex and dcomplex
  values that bli_cntx_init_skx() was setting in the context. The
  lesson here is that going forward, all subconfigurations must not set
  any blocksizes for datatypes corresponding to default/reference
  microkernels. (Note that a blocksize is left unchanged by the
  bli_cntx_set_blkszs() function if it was set to -1.)

0645f239fb Remove UT-Austin from copyright headers' clause 3.
Details:
- Removed explicit reference to The University of Texas at Austin in the
  third clause of the license comment blocks of all relevant files and
  replaced it with a more all-encompassing "copyright holder(s)".
- Removed duplicate words ("derived") from a few kernels' license
  comment blocks.
- Homogenized license comment block in kernels/zen/3/bli_gemm_small.c
  with format of all other comment blocks.

e249a00a82 Imported skx dgemm ukernel from skx-redux branch.
Details:
- Added the new bli_dgemm_skx_asm_16x14.c microkernel from the skx-redux
  branch, along with appropriate blocksizes in bli_cntx_init_skx.c and
  a prototype in bli_kernels_skx.h. (Devin has not yet written the
  sgemm analague, so for now we will continue using the older sgemm
  ukernel.)
- Updated frame/include/bli_x86_asm_macros.h with a minor change that
  was present within the skx-redux branch.

4fa4cb0734 Trivial comment header updates.
Details:
- Removed four trailing spaces after "BLIS" that occurs in most files'
  commented-out license headers.
- Added UT copyright lines to some files. (These files previously had
  only AMD copyright lines but were contributed to by both UT and AMD.)
- In some files' copyright lines, expanded 'The University of Texas' to
  'The University of Texas at Austin'.
- Fixed various typos/misspellings in some license headers.

60366a3fab Updates to knl kernels and related code.
Details:
- Imported the 24x16 knl sgemm microkernel (and its corresonding spackm
  kernel) from TBLIS and enabled its use in the knl sub-config. Also
  Added sgemm microkernel prototype to bli_kernels_knl.h.
- Updated dgemm and dpackm microkernels from TBLIS, which included an
  important change regarding the offsets array (changed from extern
  declaration to static declaration/definition).
- Activated use of level-1v and -1f zen kernels in skx and knl
  sub-configs.
- Removed some old macros no longer needed in bli_family_skx.h now that
  libmemkind support exists in configure.
- Moved bli_avx512_macros.h to frame/include and adjusted #includes in
  skx and knl kernels accordingly.
- Moved unused kernels in kernels/knl/3 to kernels/knl/3/other
  directory.
- Fixed a minor bug in the 'make' output per compile when verboseness
  is not turned on. The rule-generating function 'make-kernel-rule' was
  previously passing in the name of the config, rather than the name of
  the kernel set returned by get-config-for-kset, which could give
  misleading information to the user when the kconfig_map mapped a
  kernel set to a sub-configuration that did not share the same name.
  (This didn't affect the CFLAGS that were actually used.)
- Updated test/3m4m/Makefile, removing acml targets and renaming the
  remaining targets.
