In preparation for compiling tcg/ only once, eliminate
the all_helpers array. Instantiate the info structs for
the generic helpers in accel/tcg/, and the structs for
the target-specific helpers in each translate.c.
Since we don't see all of the info structs at startup,
initialize at first use, using g_once_init_* to make
sure we don't race while doing so.

therefore there's no need to record temps for later freeing.

All of the fpu operations are defined with TCG_CALL_NO_WG, but they
all modify FCSR0. The most efficient way to fix this is to remove
cpu_fcsr0, and instead use explicit load and store operations for the
two instructions that manipulate that value.
