This creates a helper function, _entrypoint, which invokes main() and
assigns its result into sk_FragColor. We also make sure to prevent
sk_FragColor from being dead-stripped from the code during IR
generation.
At present this is useful for allowing our SkSL test shaders to compile.

This lets us use descriptive names like `colorRed` and `colorGreen`
instead of `half4(1,0,0,1)` and `half4(0,1,0,1)`. It also lets us use
actual unknown values instead of synthesizing sorta-kinda-unknowns by
calling sqrt.

This allows uniforms to be specified without an explicit `layout(set=N)`
modifier. They will assume a default set value instead.
This turns out to fix a handful of tests in Metal/SPIR-V which were
written with GLSL in mind, or adapted from real generated GLSL code, and
didn't have layout information specified on their uniforms. It will also
make it easier to write SkSL tests using uniforms that can compile
either as a runtime effect or as plain Metal/SPIR-V code.

In most cases, this works properly and a `;` is emitted, but in one
particular case (int x, y;) we get nothing.
