Revert "Fold HTypeInfoReadVariable of instance creation."

These tests 'fail':
  language/mixin_regress_13688_test
  language/regress_18713_test

They are marked as failing due to faulty type information ($isX and
$asX) causing the wrong lookup of a type parameter of a mixin class.
The CL causes the lookup to be folded, giving the correct result.

The underlying issue needs to be fixed before we can proceed with this
CL.
