If anyone finds another recursive C path that bypasses the recursion
limiting, they can add a new crasher example.

Previously, excessive nesting in expressions would blow the
stack and segfault the interpreter. Now, a hard limit based
on the configured recursion limit and a hardcoded scaling
factor is applied.

Added a new crasher that targets mutating the underlying storage of a buffer.  All work done by Armin Rigo.

the descriptor because it may be destroyed before being used, destroyed during
the update of the dict for example.

the type MRO to avoid a crash if the MRO is changed during the lookup.

a lookup.

"if you want to make a sandbox on top of CPython, you have to fix segfaults"
so let's fix segfaults!

Last attempt to get compiler recursion crasher to fail reliably across platforms before giving up and skipping it as unreliably platform dependent

Give more info in verbose mode when checking crashers, and stress the stack even more in the compiler crasher
