Remove unused libgfortran functions

Now that the libgfortran ABI major version has been bumped, we can
remove functions for which the frontend nowadays generates inline
code.

This removes the malloc, free, exponent, fraction, nearest, rrspacing,
spacing, set_exponent and transpose intrinsics. Also the unused
store_exe_path function is removed.
