[PATCH v8 0/1] MR10464: Draft: vbscript: Return "Name redefined" error for duplicate declarations.

[Francis De Brabandere (＠francisdb)]

When a name is defined twice (Const/Const, Dim/Const, Const/Dim, Dim/Dim,
Sub vs Const/Dim, Class vs Const/Dim/Function, duplicate class members),
Windows returns VBScript error 1041 ("Name redefined"). Wine was returning
E_FAIL.

Store source locations in const_decl_t, dim_decl_t, function_decl_t, and
class_decl_t so errors point to the duplicate name. Also fix duplicate
Sub/Function/Property/Dim detection inside classes, including the case
where a Property collides with an existing Sub/Function.
