Normalize evars during bytecode compilation (fix #13841).
Otherwise, the interpreter sees already unified evars as accumulators
rather than actual constants, thus preventing the computations from
progressing.
This was caused by 6b61b63bb8626827708024cbea1312a703a54124, which removed
evar normalization. The effect went unnoticed because the computed term is
still convertible to the reduced term, except that it is the lazy
machinery that ends up reducing it, rather than the bytecode one.
So, performances became abysmal, seemingly at random.
