modernize-loop-convert to suggest usage of algorithms

Extended Description

I run modernize-loop-convert over LLVM code and looked on headers and in all cases algorithms (find, find_if, any_of, copy_if) seems better solution then loop conversion, so I think will be good idea to enhance modernize-loop-convert to suggest at least algorithm family.

I think this is not the right fit for modernize-loop-convert.

Using an algorithm vs. a loop is often a conscious decision; algorithms were often already there prior to new versions of the language.

I do think, though, that having a clang-tidy check readability-use-algorithm or something that suggests to use the right algorithm would be an excellent addition to clang-tidy.

Parasoft DTP has such check to suggest usage of algorithms instead of loops (STL-33)

Partially implemented in readability-use-anyofallof.
