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 d930ef76ea Avoid using rvalue references with trivially copyable types.
Summary:
When the dereference operator returns a value that is trivially
copyable (like a pointer), copy it. After this change, modernize-loop-convert
check can be applied to the whole llvm source code without breaking any build
or test.

Aaron Ballman 8b0583ef1b Disable several more clang-tidy modernize checkers when not compiling in C++ mode. Loop conversion would make recommendations for C code, so added a test to ensure that does not happen. The pass by value, use auto and replace auto_ptr checkers would not make recommendations for C code, and are disabled for performance reasons, but do not require an extra test.
