cpu.x86.64.bootstrap: save all the regs on signal
...
Appears to fix another sporadic crash from mason on x86-64. There's no reason to cut corners here, really.

cpu.x86.bootstrap: don't safepoint in a safepoint
...
Safepointing in the signal-handler primitive causes a crash if the safepoint is guarded and the signal being handled was raised by a safepoint. Put our own RET in the subprimitive to bail out before the standard epilog gets written out. This tentatively appears to fix #349 .

We also need to save C ABI volatile registers before calling the signal handler in order to be able to reliably resume. Add signal-handler and leaf-signal-handler subprimitives to preserve volatile registers before invoking the signal handler C function.

compiler.cfg: Reading the return value of a float-returning function on x86-32 had a side effect of popping the x87 stack, so it was not correct for DCE to just eliminate this if the return value was not used.
