score: Delete _CPU_Context_Fp_start()

Since the FP area pointer is passed by reference in
_CPU_Context_Initialize_fp() the optional FP area adjustment via
_CPU_Context_Fp_start() is superfluous.  It is also wrong with respect
to memory management, e.g. pointer passed to _Workspace_Free() may be
not the one returned by _Workspace_Allocate().

Close #1400.
