  Fix clearing the program's validation-related cache too early
  
  When attempting to link a new program, the program must be marked
  as unlinked, but the validation-related caching should not be
  cleared yet, since we can still use the previously linked program
  if linking fails at this point.
  
  Added an angle end2end test which fails without this fix and
  passes with this fix.
  
  Fixes the following WebGL 1.0.4 test with SwANGLE:
  conformance/programs/program-test.html
