    Message : Get direct-to-Metal backend to run angle_end2end_tests. Cherry-pick nameless struct fix from Apple in https://bugs.webkit.org/show_bug.cgi?id=227482 . Fix SeparateCompoundStructDeclarations pass to stop generating multiple declarations; thanks syoussefi@ for advice. Incorporate additional passes from TranslatorVulkan (MonomorphizeUnsupportedFunctionsInVulkanGLSL, RewriteArrayOfArrayOfOpaqueUniforms, SeparateStructFromUniformDeclarations) needed by RewriteStructSamplers pass in TranslatorMetalDirect. Fixes many assertion failures in GLSL tests. Moved these passes out of tree_ops/vulkan. Thanks again to syoussefi@ for advice and help. Disable a validation check related to the RewritePipelines pass. Skip two tests that were failing for other reasons. With these changes, angle_end2end_tests runs to completion when the direct-to-Metal backend is turned on. There are still ~1300 failures of the ~4000 tests which will be investigated next.

// MonomorphizeUnsupportedFunctions: Monomorphize functions that are called with
// parameters that are incompatible with both Vulkan GLSL and Metal:
//
// - Samplers in structs
// - Structs that have samplers
// - Partially subscripted array of array of samplers
// - Partially subscripted array of array of images
// - Atomic counters
// - samplerCube variables when emulating ES2's cube map sampling
// - image* variables with r32f formats (to emulate imageAtomicExchange)
//
// This transformation basically duplicates such functions, removes the
// sampler/image/atomic_counter parameters and uses the opaque uniforms used by the caller.
