  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.
