I'm afraid you cannot turn inline functions into indirect calls like
this in hot paths.
One alternative would be to hoist the function call to the beginning of
cpu_exec, and ensure that any place that modifies the result calls
cpu_exit. It may be a problem for SPARC's npc stuff, for which I have
no idea how it works.
Another is to change cpu-exec.c into a file that is #included by
target-*/helper.c or something like that. This way cpu-exec.c can still
use the inline functions.
