82065d667f remove SkRefCnt safeRef() and safeUnref(), and replace the call-sites with 
SkSafeRef() and SkSafeUnref().

This is basically a bug waiting to happen. An optimizing compiler can remove
checks for null on "this" if it chooses. However, SkRefCnt::safeRef() relies on
precisely this check...

void SkRefCnt::safeRef() {
    if (this) {
        this->ref();
    }
}

Since a compiler might skip the if-clause, it breaks the intention of this
method, hence its removal.

static inline void SkSafeRef(SkRefCnt* obj) {
    if (obj) {
        obj->ref();
    }
}

This form is not ignored by an optimizing compile, so we use it instead.

512a87641f make the 16bit cache larger, to handle multiple colors in the gradient w/o 
obvious artifacts. We need a more comprehensive fix for all gradients (32bit
and 16bit) when we have a large number of colors (or they are spaced out very
non-linearly), to avoid banding.

3c9b2a4a0e expand SkShader's flag kConstInY to 16 and 32 variants, allowing a shader 
(like gradients) to support predithering. If they do, then they would suppress
kConstInY16, since they no longer are const.

The blitters now check for each flag separately, so we don't have to give up
const-in-Y in the 32bit case, since in that mode we don't care about dithering.

5119bdb952 add shader flag kConstInY_Flag 
this signals blitters that the shader will return the same results for a given
x value, independent of y. Useful inside blitRect(), where it can cache the
first call to shadeSpan() and reuse it on all subsequent scans. Works with
(non-rotated) linear-gradients, and Nx1 bitmaps.
