Instead of generating separate object files for each permutation of
defines for a source file, GenerateNamedObjects now writes an entirely
new source file and inserts the defines as #define c statements.

This solves a problem I ran into with ar.exe where it was refusing to
link objects that had the same filename despite having different paths.

Added zherk_k sources to driver/level3.

Added loop to build objects with different KERNEL defines.

This will generate obj files for SINGLE/DOUBLE/COMPLEX/DOUBLE COMPLEX.

MSVC doesn't inmplement C99, so can't use the inline keyword. __inline
appears to work in MSVC and GCC.

Made float type optional for GenerateNamedObjects.

Called GenerateNamedObjects for a couple of driver/others files that
needed NAME/CNAME set.

It sets DBLAS_OBJS directly to save a bunch of list appending in the
CMakeLists.txt files.

Added some kernel and driver/others objects.

The level3 object names should now be correct.

Fixed the code array not getting reset on subsequent AllCombinations
calls.

Since the objects are the same, could generate SINGLE/COMPLEX/etc here
without having to rewrite all the object enumeration code again.

This function takes a set of sources and a set of preprocessor
definitions. It will iterate over the sources and build an object
file for each combination of preprocessor definitions for each
source file.

Added a rather convoluted CMake function to find all combinations
of a given list. This will be useful for the object files that are
compiled multiple times with different combinations of preprocessor
definitions.

Still isn't parsed into CMake variables, and getarch_2 needs to
get the same treatment.

get_nprocs() is a GNU convenience function equivalent to POSIX2008
sysconf(_SC_NPROCESSORS_ONLN); the latter should be available in unistd.h
on any current *nix. (OS X supports this call since 10.5, and FreeBSD
currently supports it. But this commit does not change FreeBSD or OS X
versions.)
