Hey Jaro,
This is the port of the for-in stuff to typed lowering. It's pretty much
straight forward for now.
Please take a look.
Thanks,
Benedikt
Description:
[turbofan] First steps towards optimizing for-in loops.
This is basically a port of the majority of optimizations that are
applied to for-in in full codegen. But it is not done during graph
building, but instead during typed lowering, which way less adhoc than
what the other compilers do.
