02e19de346 Added shape of implementation for last missing VSCALEF* AVX-512 instructons. 
The softfloat implementation is still missing (only corner cases are supported).
Extend softfloat floatNN_class methods to distinguish between SNaN and QNaN.

58019a1649 Renamed "ltdl.h" to "ltdl-bochs.h" to avoid conflicts with the include file 
that is a part of the libtool package. Updated Makefile dependencies.
TODO: check if we can get rid of the ltdl*.* files (this would be possible if
the ltdl library is always available if libtool is present).
