When SPIR-V generates function calls to an intrinsic, it assumes that it can get a pointer to out-parameters referenced by the intrinsic. This does not account for swizzled out-parameters; these are valid lvalues, but do not work with getPointer(). The two intrinsics supported by SkSL which have an out-parameter are frexp and modf, so these tests were fleshed out to trigger the error. Neither of these are supported in ES2, though, so we cannot test them via Runtime Effects.
