80cae358b0 Adds a modified f2c-generated C implmentation for BLAS. 
This adds an optional implementation for the BLAS library that does
not require the use of a FORTRAN compiler. It can be enabled with
EIGEN_USE_F2C_BLAS.

The C implementation uses the standard gfortran calling convention
and does not require the use of -ff2c when compiled with gfortran.

bfdd9f3ac9 Made the blocking computation aware of the l3 cache 
Also optimized the blocking parameters to take into account the number of threads used for a computation

10447a7b57 mv blas.h to src/misc such that it would be possible to use any blas libraries, 
however, this requires some more works:
 - add const qualifiers in the declarations of blas.h
 - add the possibility to add a suffix to blas function names
