Fix non-conforming code.

[karlosz]

According to the LOAD-TIME-VALUE entry for CLHS http://clhs.lisp.se/Body/s_ld_tim.htm, "It is guaranteed that the evaluation of form will take place only once when the file is loaded, but the order of evaluation with respect to the evaluation of top level forms in the file is implementation-dependent." Therefore, doing LOAD-TIME-VALUE of a function call where the function is defined in the same file is not portable code.

This is important to fix because old versions of CMU CL do take advantage of this fact, and future versions of SBCL may as well.
