Tests fail because hash(:F) != hash(:F, UInt(0))

[gafter]

The tests assume that hash(:F) is the same value as hash(:F, UInt(0)). That has not been the case since Julia added an optimization for the former:

hash(x::Symbol) = objectid(x)

Since the generated code uses the latter, the tests that verify the generated hash code should also use the former for comparison.

Tests are now passing.
