    • compiler: resolve importing ambiguity for more complex function calls · 6e81d34e 
          
    Tweak the exporter for inlinable function bodies to work around a
    problem with importing of function calls whose function expressions
    are not simple function names. In the bug in question, the function
    body exporter was writing out a function call of the form
    
           (*(*FuncTyp)(var))(arg)
    
    which produced an export data representation of
    
           *$convert(<type 5>, var)(x)
    
    which is hard to parse unambiguously. Fix: change the export data
    emitter to introduce parens around the function expression for more
    complex calls.
    
    Testcase for this bug is in CL 197217.
    
    Fixes golang/go#34503.
