deb0c5e66c Two small changes:
- Use co->... instead of f->f_code->...; save an extra lookup of what
we already have in a local variable).

- Remove test for nlocals > 0 before setting fastlocals to
f->f_localsplus; 0 is a rare case and the assignment is safe even
then.

d0eb429b88 Plug a leak with calling something other than a function or method is
called with keyword arguments -- the keyword and value were leaked.
This affected for instance with a __call__() method.

Bug reported and fix supplied by Jim Fulton.

950361c6ca Patches for (two forms of) optional dynamic execution profiling --
i.e., counting opcode frequencies, or (with DXPAIRS defined) opcode
pair frequencies.  Define DYNAMIC_EXECUTION_PROFILE on the command
line (for this file and for sysmodule.c) to enable.

8c5df06ec7 Change the control flow for error handling in the function prelude to
jump to the "Kill locals" section at the end.  Add #ifdef macintosh
bandaid to make sure we call sigcheck() on the Mac.

43f1b8d6e4 Added optional interface for dynamic execution profile (to be gathered
in ceval.c).

b3f515af64 Get the line number from PyCode_Addr2Line instead of believing
tb_lineno.  Store it in tb_lineno for the user.

da4eb5c3b5 Instead of emitting SET_LINENO instructions, generate a line number
table which is incorporated in the code object.  This way, the runtime
overhead to keep track of line numbers is only incurred when an
exception has to be reported.

a4240132ec Kill all local variables on function return. This closes a gigantic
leak of memory and file descriptors (thanks for Roj for reporting
that!).  Alas, the speed goes down by 5%. :-(

70d44787a3 Only call sigcheck() at the ticker code if we don't have true signals.
This is safe now that both intrcheck() and signalmodule.c schedule a
sigcheck() call via Py_AddPendingCall().

This gives another 7% speedup (never run such a test twice ;-).

768360243a Changes for frame object speedup:
- get fastlocals differently
- call newframeobject() with fewer arguments
- toss getowner(), which was unused anyway

7b89b6a660 Intern all names and varnames in newcodeobject(), plus those string
literals that look like identifiers.  Also intern all strings used as
names during the compilation.

3dfd53b4c8 Add "if (x != NULL) continue;" (or similar for err==0) before the
break to most cases, as suggested by Tim Peters.  This gives another
8-10% speedup.

62f7d15d0b Use the stack size from the code object and the CO_MAXBLOCKS constant
from compile.h.  Remove all eval stack overflow checks.

8b993a98db Add co_stacksize field to codeobject structure, and stacksize argument
to PyCode_New() argument list.  Move MAXBLOCKS constant to conpile.h.

Added accurate calculation of the actual stack size needed by the
generated code.

Also commented out all fprintf statements (except for a new one to
diagnose stack underflow, and one in #ifdef'ed out code), and added
some new TO DO suggestions (now that the stacksize is taken of the TO
DO list).
