  Vulkan: Optimize shader source macro replacement
  
  @@ LAYOUT-xx @@ and @@ QUALIFIER-xx @@ macros are generated by the
  compiler when emitting Vulkan GLSL.  These macros are replaced at link
  time in the Vulkan backend.
  
  Previously, this replacement was done through calls to
  angle::ReplaceSubstring, reiterating over the whole source on every
  replacement.  This CL does a prepass on the input source and chunks it
  up in blocks.  Search is optimized as only blocks of a certain type are
  string-compared (skipping large chunks of shader text).  Replace is
  optimized as the whole shader is not shifted left or right on every
  replacement.
  
  Additionally, this CL modifies the layout macro to the following format:
  
  	@@ LAYOUT-xx(extra, args) @@
  
  This is used in a follow up CL to have the compiler provide additional
  layout qualifiers.
