const half3x3 testMatrix3x3 = half3x3(1, 2, 3, 4, 5, 6, 7, 8, 9);
half    testScalar    = half (testMatrix3x3);
half2   testVec2      = half2(testMatrix3x3);

Add support for matrix-to-vector conversions in SkSL. GLSL supports casting vec4 into mat2 and vice versa, so SkSL should have equivalent support. This CL allows the Compound constructor to take a matrix as input, and fixes up backends to do the right thing when a matrix shows up in the compound-constructor path.

Shore up matrix/vector conversion tests. The tests now check bool4-mat2 conversions, which fortunately do work, and the vector-to-matrix tests include int and bool conversions as well.
