### Compilation failed:

error: 2: unknown identifier 'x'
1 error
Add unit test for self-referential initializer expressions. These don't compile in GLSL, so they shouldn't compile in SkSL either-- and fortunately, they do not. (In C++, and consequently in Metal, these expressions are considered legal by the grammar and do compile, but generate garbage output.)
