Reland "Eliminate unreachable code during optimization."

This is a reland of c6260f974261ee9fb5dc9573669559d728a856e8

Problematic DeadReturn.sksl test cases have been moved to DeadReturnES3.

Original change's description:
> Eliminate unreachable code during optimization.
>
> The Adreno 5xx and 6xx previously failed the SkSLStaticSwitchInline
> test; the driver struggled to interpret code with multiple return
> statements in a row. We now detect unreachable statements and eliminate
> them.
