r194188 - This patch implements capturing of variables within generic lambdas.

[Amara Emerson]

Hi Faisal,

+void LambdaScopeInfo::getPotentialVariableCapture(unsigned Idx, VarDecl
*&VD, Expr *&E) {
+  assert((Idx >= 0 && Idx < getNumPotentialVariableCaptures()) &&
+    "Index of potential capture must be within 0 to less than the "
+    "number of captures!");

Idx will always be >= 0 since it's unsigned. Compiler warning flagged this
up.

Cheers,
Amara
