Angel Garcia Gomez 432ff5e205 Handle correctly containers that are data members in modernize-loop-convert.
Summary:
I recently found that the variable naming wasn't working as expected with containers that are data members. The new index always received the name "Elem" (or equivalent) regardless of the container's name.
The check was assuming that the container's declaration was a VarDecl, which cannot be converted to a FieldDecl (a data member), and then it could never retrieve its name.

This also fixes some cases where the check failed to find the container at all (so it didn't do any fix) because of the same reason.

Angel Garcia Gomez bb9ca54bbe Another patch for modernize-loop-convert.
Summary:
1. Avoid converting loops that iterate over the size of a container and don't use its elements, as this would result in an unused-result warning.
2. Never capture the elements by value on lambdas, thus avoiding doing unnecessary copies and errors with non-copyable types.
3. The 'const auto &' instead of 'auto &' substitution on const containers now works on arrays and pseudoarrays as well.
4. The error about multiple replacements in the same macro call is now documented in the tests (not solved though).
5. Due to [1], I had to add a dummy usage of the range element (like "(void) *It;" or similars) on the tests that had empty loops.
6. I removed the braces from the CHECK comments. I think that there is no need for them, and they confuse vim.

Angel Garcia Gomez bd0ec69e0a Avoid repeated replacements on loop-convert check.
Summary: The InitListExpr subtree is visited twice, this caused the check to do multiple replacements. Added a set to avoid it.

Angel Garcia Gomez 8d01772dae Two more fixes to loop convert.
Summary: Ensure that the alias has the same type than the loop variable. Now it works with lambda captures.
