Here are the gcc docs for this gnu-tension:
http://gcc.gnu.org/onlinedocs/gcc/Nested-Functions.html

Is this worth supporting in clang and LLVM?  My understanding of the
implementation is that you emit snippet of code to the stack which loads the
address of the parent stack frame and jumps into the nested function.

It seems LLVM already supports trampolines, so this would mostly be frontend
work.
