ConditionalClauseInitializerScope often create redundant scopes, however, they are needed to correctly represent the scopes in an expression such as: if case .something(let foo), let foo = foo. This patch changes SILGen to lower them 1:1 from ASTScopes. rdar://110841130
The previous lazy discovery did not always work because sometimes a debug_value is emitted before the first SIL instruction in the variable's scope. rdar://110841130
