[PATCH] D33895: [Support] Add TempFailureRetry helper function

[Pavel Labath via Phabricator via llvm-commits]

I've renamed the function.

Decltype trick will not work for the fail value because F and As... are not yet
defined at that point (although this isn't the reason why I originally added the
extra template param). It's possible to achieve it with std::result_of though.

I've replaced the other uses of decltype with result_of as I think it would be
confusing to use both.
