Respect C++17 copy elision; previously it would generate destructor calls
for elided temporaries, including in initialization and return statements.
Don't generate duplicate destructor calls for statement expressions.
Fix destructors in initialization lists and comma operators.
Improve printing of implicit destructors.
Patch by Nicholas Allegra!

We don't yet support this for the case where a range-based for loop is
implicitly rewritten to an ObjC for..in statement.

Loop condition variables, eg.
while (shared_ptr<int> P = getIntPtr()) { ... })
weren't handled in r324794 because they don't go through the common
CFGBuilder::VisitDeclStmt method. Which means that they regressed
after r324800.
Fix the regression by duplicating the necessary construction context scan in
the loop visiting code.

This patch adds two new CFG elements CFGScopeBegin and CFGScopeEnd that indicate
when a local scope begins and ends respectively. We use first VarDecl declared
in a scope to uniquely identify it and add CFGScopeBegin and CFGScopeEnd elements
into corresponding basic blocks.
