    x86, arm: Allow fpu_kern_enter/leave while cold.

    Normally these are forbidden above IPL_VM, so that FPU usage doesn't
    block IPL_SCHED or IPL_HIGH interrupts.  But while cold, e.g. during
    builtin module initialization at boot, all interrupts are blocked
    anyway so it's a moot point.

    Also initialize x86 cpu_info_primary.ci_kfpu_spl to -1 so we don't
    trip over an assertion about it while cold -- the assertion is meant
    to detect reentrance into fpu_kern_enter/leave, which is prohibited.

    Also initialize cpu0's ci_kfpu_spl.
