Slight tweak: in string_hash(), if the hash hasn't been computed yet,
...
and if there's a pointer to an interned version of the string, use its
hash and store its hash in this object, rather than recomputing it.

Small lookmapping nits:

- remove bogus initialization using uninitialized i
- derive initial incr from hash
- copy mp->ma_table into a local variable

Changed the lookup algorithm again, based on Reimer Behrends's post.
...
The table size is now constrained to be a power of two, and we use a
variable increment based on GF(2^n)-{0} (not that I have the faintest
idea what that is :-) which helps avoid the expensive '%' operation.
Some of the entries in the table of polynomials have been modified
according to a post by Tim Peters.

When a recycled frame has more local+stack slots than needed,
...
give the extra slots to the stack rather than than forgetting about
them (this reduces the number of reallocs done).

Forget keeping track of whether a dictionary contains all interned

string keys. Just doing a pointer compare before the string compare
(in fact before the hash compare!) is just as fast.

Changes that appear to give another 12% speedup.
...
Rather than allocating a list object for the fast locals and another
(extensible one) for the value stack and allocating the block stack
dynamically, allocate the block stack with a fixed size (CO_MAXBLOCKS
from compile.h), and stick the locals and value stack at the end of
the object (this is now possible since the stack size is known
beforehand). Get rid of the owner field and the nvalues argument --
it is available in the code object, like nlocals.
This requires small changes in ceval.c only.
