All compiler fixes to get ir branch work with falcor feature demo.

- support overloaded generic function. this involves adding a new expression type, `OverloadedExpr2` to hold the candidate expressions for the generic function decl being referenced.
- make BitNot a normal IROp instead of an IRPseudoOp
- make sure we clone the decorations of parameters when cloning ir functions
- propagate geometry shader entry point attributes (`[maxvertexcount]` and `[instance]`) through HLSL emit
- IR emit: handle geometry shader entry-point parameter decorations, such as 'triangle'.
- IR emit: treat geometry shader stream output typed ir value as `should fold into use`.
