Work around missing __mulodi4() on ARMv7 + Clang builds.

__mulodi4() is roughly,

    int64_t __mulodi4(int64_t a, int64_t b, int* overflow) {
        int64_t result = a*b;
        *overflow = did_overflow(result);
        return result;
    }

It's used by Clang's __builtin_smulll_overflow(), which is basically the same
except it swaps the positions of the return value and the out parameter.

DNG SDK in turn uses __builtin_smulll_overflow().

When building ARMv7 binaries with Clang, __mulodi4() turns up as a missing symbol.
That's because it's defined in a separate compiler-rt library.  I have not been
able to link that.  Instead, I've provided our own trivial __builtin_smulll_overflow().

Before this patch both nanobench and DM failed dynamically linking __mulodi4().  After this patch nanobench runs for a while, eventually segfaulting.  DM immediately segfaults.

If there are no issues, this version will be released May 26.

Let's start testing with it, so we are ready to update Chrome when
it is available.

We now have some blits that will process the color table.

If we erroneously report that the size of the color table is 256,
we will do extra work and annoy MSAN.

Remove workarounds initializing command buffer EGL

The eglDisplay() of command buffer EGL implementation now does not
allocate a new EGL display per call, rather just returns the global.

The EGL implementation is fixed as part of bug 581634.

Removes eglTerminate call, as it's should not be used in Skia at the
moment. The call will terminate all of EGL, which is not intendend. The
previous usage was only due to incorrect implementation of the API.  Not
added back to anywhere else, leaking EGL globals is as
designed. Discussed in https://chromiumcodereview.appspot.com/1733323002.

Convert GrClip to an abstract base class

Converts GrClip to an abstract base class and adds a "GrFixedClip"
implementation. GrFixedClip denotes a clip implemented with fixed-

"fClipMode" member from GrClipMaskManager, and in the future will
