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.

5fec95b99f Implemented mixed-datatype support for gemm.
Details:
- Implemented support for gemm where A, B, and C may have different
  storage datatypes, as well as a computational precision (and implied
  computation domain) that may be different from the storage precision
  of either A or B. This results in 128 different combinations, all
  which are implemented within this commit. (For now, the mixed-datatype
  functionality is only supported via the object API.) If desired, the
  mixed-datatype support may be disabled at configure-time.
- Added a memory-intensive optimization to certain mixed-datatype cases
  that requires a single m-by-n matrix be allocated (temporarily) per
  call to gemm. This optimization aims to avoid the overhead involved in
  repeatedly updating C with general stride, or updating C after a
  typecast from the computation precision. This memory optimization may
  be disabled at configure-time (provided that the mixed-datatype
  support is enabled in the first place).
- Added support for testing mixed-datatype combinations to testsuite.
  The user may test gemm with mixed domains, precisions, both, or
  neither.
- Added a standalone test driver directory for building and running
  mixed-datatype performance experiments.
- Defined a new variation of castm, castnzm, which operates like castm
  except that imaginary values are not touched when casting a real
  operand to a complex operand. (By contrast, in these situations castm
  sets the imaginary components of the destination matrix to zero.)
- Defined bli_obj_imag_is_zero() and substituted calls in lieu of all
  usages of bli_obj_imag_equals() that tested against BLIS_ZERO, and
  also simplified the implementation of bli_obj_imag_equals().
- Fixed bad behavior from bli_obj_is_real() and bli_obj_is_complex()
  when given BLIS_CONSTANT objects.
- Disabled dt_on_output field in auxinfo_t structure as well as all
  accessor functions. Also commented out all usage of accessor
  functions within macrokernels. (Typecasting in the microkernel is
  still feasible, though probably unrealistic for now given the
  additional complexity required.)
- Use void function pointer type (instead of void*) for storing function
  pointers in bli_l0_fpa.c.
- Added documentation for using gemm with mixed datatypes in
  docs/MixedDatatypes.md and example code in examples/oapi/11gemm_md.c.
- Defined level-1d operation xpbyd and level-1m operation xpbym.
- Added xpbym test module to testsuite.
- Updated frame/include/bli_x86_asm_macros.h with additional macros
  (courtsey of Devin Matthews).

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.

7ed415824d Updated copyright headers (continued).
Details:

  Meant to include this change in previous commit.

5c2c6c8561 Updated copyright headers to contain "at Austin".
Details:
- Updated copyright headers to include "at Austin" in the name of the
  University of Texas.
- Updated the copyright years of a few headers to 2014 (from 2011 and
  2012).

392428dea4 Added "ri" scalar macros.
Details:
- Added set of basic scalar macros that take arguments' real and
  imaginary components separately, named like the previous set except
  with the "ris" (instead of "s") suffix.
- Redefined the previous set of scalar macros (those that take arguments
  "whole") in terms of the new "ri" set.
- Renamed setris and getris macros to sets and gets.
- Renamed setimag0 macros to seti0s.
- Use bli_?1 macro instead of a local constant in bla_trmv.c, bla_trsv.c.

4e80ad28c9 Added support for C99 complex types/arithmetic.
Details:
- Added support for C99 complex types to bli_type_defs.h and overloaded
  complex arithmetic to the scalar-level macros in include/level0. This
  includes a somewhat substantial reorganization and re-layering of much
  of the existing machinery present in the level0 macros.
- Added new #define for BLIS_ENABLE_C99_COMPLEX to bli_config.h files,
  commented-out by default, which optionally enables the use of built-in
  C99 complex types and arithmetic.
- Minor changes to clarksville and reference configs' make_defs.mk files.
- Removed macro definitions from bli_param_macro_defs.h which was not being
  used (bli_proj_dt_to_real_if_imag_eq0).

4b7e7970f1 Migrated integer usage to stdint.h types.
Details:
- Changed the way bli_type_defs.h defines integer types so that dim_t,
  inc_t, doff_t, etc. are all defined in terms of gint_t (general signed
  integer) or guint_t (general unsigned integer).
- Renamed Fortran types fchar and fint to f77_char and f77_int.
- Define f77_int as int64_t if a new configuration variable,
  BLIS_ENABLE_BLIS2BLAS_INT64, is defined, and int32_t otherwise.
  These types are defined in stdint.h, which is now included in blis.h.
- Renamed "complex" type in f2c files to "singlecomplex" and typedef'ed
  in terms of scomplex.
- Renamed "char" type in f2c files to "character" and typedef'ed in terms
  of char.
- Updated bla_amax() wrappers so that the return type is defined directly
  as f77_int, rather than letting the prototype-generating macro decide
  the type. This was the only use of GENTFUNC2I/GENTPROT2I-related macros,
  so I removed them. Also, changed the body of the wrapper so that a
  gint_t is passed into abmaxv, which is THEN typecast to an f77_int
  before returning the value.
- Updated f2c code that accessed .r and .i fields of complex and
  doublecomplex types so that they use .real and .imag instead (now that
  we are using scomplex and dcomplex).
