Mike Klein e083f7c9f2 Reland "remove SkCanvas::kIsOpaque_SaveLayerFlag" 
This reverts the revert 9ff8c8c073.

Original:

    This is a performance-only hint that no one but fuzzers
    is using.  It's even explicitly filtered out in Android.

    The fuzzers have noticed they can trick us into allocating
    uninitialized memory and treating it as opaque, blending
    uninitialized pixels, etc.

    Since no one's using this, we can just kill the bit.

    Bug: skia:7566, chromium:808830
