    Add test (only) to assure that #11535 is fixed
    
    Ticket #11535 dealt with derived Read instances of infix Unicode
    value constructors. GHC 7.10.3 used to derive (Read/Show)
    instances so that `read . show` for values of such types had no
    parse.
    
    The issue has been fixed by other compiler update. This patch
    adds only tests, so that derived instance of Read/Show for infix
    Unicode value constructors has correct parse, satisfying Haskell
    2010 Specification.
    
    Resolves: #11535
    
    Test Plan: `make test TEST=T11535`
