Ben Clayton 10d5c6a6b6 ast: Have all tests derive from new TestHelper 
It doesn't actually do anything (yet), but will hold the context and

the usage of UintLiteral.

dan sinclair 253ee1b3ef Fixup IntLiteral names. 
This CL fixes the IntLiteral name to contain the type of the literal.
This keeps i32 and u32 from fighting over a given name. Now, the name
ends up being __int__i32_0 instead of __int_0.
