Ian Lance Taylor 2dab5d909f runtime: use a fence instruction before rdtsc
This implements the same choices made in the gc runtime, except that
    for 32-bit x86 we only use the fence instruction if the processor
    supports SSE2.
    
    The code here is hacked up for speed; the gc runtime uses straight
    assembler.
