  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.
