Fix restoring cpl in the swi_ast_phantom case.  The system sometimes
returned to user mode without enabling ASTs.  The problem fixed itself
at the next syscall or non-FPU trap, if any.  It hung the system for
a test process that masked SIGFPE's and divided by zero.  The faulting
division was returned to endlessly and this gave plently of opportunities
for the swi_ast_phantom case to be reached; after it was reached the
system hung because the ASTs for preemption and SIGINT handling were
disabled.
