* void __cilkrts_fence(void)
*
* Executes an MFENCE instruction to serialize all load and store instructions
* that were issued prior the MFENCE instruction. This serializing operation
* guarantees that every load and store instruction that precedes the MFENCE
* instruction is globally visible before any load or store instruction that
* follows the MFENCE instruction. The MFENCE instruction is ordered with
* respect to all load and store instructions, other MFENCE instructions, any
* SFENCE and LFENCE instructions, and any serializing instructions (such as
* the CPUID instruction).
