Artem Dergachev d18639bd13 [CFG] [analyzer] Simplify lifetime-extended temporary construction contexts. 
When a temporary object is materialized and through that obtain lifetime that
is longer than the duration of the full-expression, it does not require a
temporary object destructor; it will be destroyed in a different manner.

Therefore it's not necessary to include CXXBindTemporaryExpr into the
construction context for such temporary in the CFG only to make clients
throw it away.

// This file tests how we construct two different flavors of the Clang CFG -
// the CFG used by the Sema analysis-based warnings and the CFG used by the
// static analyzer. The difference in the behavior is checked via FileCheck
// prefixes (WARNINGS and ANALYZER respectively). When introducing new analyzer
// flags, no new run lines should be added - just these flags would go to the
// respective line depending on where is it turned on and where is it turned
// off. Feel free to add tests that test only one of the CFG flavors if you're
// not sure how the other flavor is supposed to work in your case.
