Add print format macros for 64bit integer builds to LAPACKE (Reference-LAPACK PR 700)

Fix implicit conversions and unused variables in LAPACKE and TESTING (Reference-LAPACK PR 703)

Add a BLAS3-based triangular Sylvester equation solver (Reference-LAPACK PR 651)

Fix leading dimension check of eigen-/Schur vectors in LAPACKE (Reference-LAPACK PR 665)

long's in windows are 4 bytes (MSVS, intel compilers). Use int64_t and int32_t
to ensure 8 byte integers for ILP interface.

support 8 byte integer flag for intel ifort compiler

Avoid allocating the transposed triangular matrix in LAPACKE_xlantr_work (Reference-LAPACK 382)

Removed spurious checks for INFO in xLACPY,xLASET after routines not returning any,and redundant requirements for ldvt in xGESVD_WORK

Based on how the surrounding functions in lapack.h are handling the
parameters, particularly the ?ggsv?3-variants of the affected functions

* Fix misnaming of LAPACK_?ggsvp and ?ggsvd function prototypes as LAPACKE_

* Drop the LAPACKE matrix_layout parameter from the argument lists, change ints to pointers and add missing work arguments.

The problem is that OpenBLAS sets the LAPACKE_LIB and the TMGLIB to the
same object and uses the `ar` feature to update the archive file. If the
underlying filesystem does not have sub-second timestamp resolution and
the system is fast enough (or `ccache` is used), the timestamp of the
builds which should be added to the previously generated archive is the
same as the archive file itself and therefore `make` does not update the
archive.

Since OpenBLAS takes care to not run the different targets updating the
archive in parallel, the easiest solution is to declare the respective
targets `.PHONY`, forcing `make` to always update them.

LAPACKE interfaces for Aasen's functions now call ?sytrf_aa and ?hetrf_aa instead of ?sytrf and ?hetrf

Copied from Reference-LAPACK/lapack#249, this fixes out-of-bounds memory accesses
in the nancheck calls of the LAPACKE lacgv, lassq,larfg,larfb,larfx and mtr functions

The macOS ar aborts when it gets called with no input, see #1398
