Subject: 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`.
