[cfe-dev] Getting all variable declaration which is inside a loop

[mats petersson via cfe-dev]

I'm reasonably sure there is no "magic" way to find this. You can use an
AST Matcher to find loops, but you then have to step through the content of
the loop. Or you can use a RecursiveASTVisitor, and find the
for-statements, then find variable declarations within that, for example
using a "map" to track which loop it is that contains what declarations.

RecursiveASTVisitor example:
