Subject: [C++11] Replacing CallArgList writeback iterators with iterator_range writebacks... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=52fa036b2ec930e88a23db731b194ef1e53114d6;p=clang

[C++11] Replacing CallArgList writeback iterators with iterator_range writebacks(). Updating all of the usages of the iterators with range-based for loops, and removing the no-longer-needed iterator versions.
