81e3bb33a0 Defer freeing pre-grown stacks when using them in native calls 
If the stack needs to grow during a native function call that has
taken a pointer into the stack as an argument, defer freeing this
copy of the stack until the outermost such call returns. The new
stack will always point to new memory, as we can not call realloc
in this case, and if repeated nested native function calls result
in multiple stack growths then several copies of the stack may
persistent in memory simultaneously, but we do not need to trouble
native function implementations with the possibility that their
arguments may become invalid, and we do not need to produce copies
of the stack when calling them.

This resolves a long-standing issue with resizable stacks where
native function calls always entailed a memcpy() penalty, and calls
with many arguments also had malloc()/free() overhead for heap
allocated stack copies.

With this change, performance improves, as the wrapper checks around
stack growth are uncommon, so their overall cost is less than the
repeated moving of arguments around for native function calls.

6613db6cd4 Implement slice objects, slice stepping 
This is an initial implementation of slice stepping and slice objects.
The __getslice__, __setslice__, and __delslice__ methods have been removed.
Slice expressions are now turned into slice objects with the OP_SLICE instruction.
Slice objects have a start, end, and step, all of which default to None.
Slice objects are passed to __getitem__, et al., as a normal parameter.

Support for slices in list.__getitem__, str.__getitem__, and bytes.__getitem__ has
been implemented.
