Issue #196: excessive proof-checking times in .v files generated by clightgen
The check that "build_composite_env composites = OK (make_composite_env composites)" is taking time exponential on the number of struct/union definitions, at least on the example provided in #196.
The solution implemented in this commit is to use computational reflection more efficiently, just to check that "build_composite_env composites" is of the form "OK _". From there, a new function Clightdefs.mkprogram produces the appropriate Clight.program without additional computation.
