[New-bugs-announce] [issue45963] Embed interpreter frame in generator.

[Mark Shannon]

New submission from Mark Shannon <mark at hotpy.org>:

Currently, the InterpreterFrame for a generator is allocated on the heap separately from the generator.
This means that 2 allocations are needed to create a generator, and an extra indirection is needed to get from the generator to the frame.

By embedding the frame in the generator, we only need one alloaction, we save an indirection *and* the code gets simpler: transferring the frame from generator to frame object is just a single memcpy.
