// EmulateMutableFunctionParams: If function parameters are modified
// in the function body, they are replaced with temporary copies, since
// function parameters are always immuable in WGSL.
//
// Example:
//
// vec4 doFoo(Foo foo, float zw)
// {
//     foo.x = foo.y;
//     return vec4(foo.x, foo.y, zw, zw);
// }
//
// Result:
//
// vec4 doFoo(Foo foo, float zw)
// {
//     Foo sbc7 = foo;
//     sbc7.x = sbc7.y;
//     return vec4(sbc7.x, sbc7.y, zw, zw);
// }
//
// NOTE: this an be deleted if WGSL standardized mutable function parameters.
