    When determining the type of an index for a string/array indexing
    expression, the gofrontend would disallow floating-point and complex
    values even if they were integral and throw an internal error.  This
    patch changes gofrontend to use an integral type context when
    determining the types of a string/array index.
    
    Fixes golang/go#11545.

This code is not used anymore after we removed the previous loop optimizer (not
based on the ISL scheduler.)  We will add back the detection of commutative
reductions after we improve the code generation of scalar dependences (by not
going out of SSA for scalar dependences just to expose them to the data
dependence graph.)

Patch passed bootstrap and check on x86_64-linux with ISL-0.15.
