effde12f5f Speed-up dictionary constructor by about 10%. 
New opcode, STORE_MAP saves the compiler from awkward stack manipulations
and specializes for dicts using PyDict_SetItem instead of PyObject_SetItem.

Old disassembly:
              0 BUILD_MAP                0
              3 DUP_TOP
              4 LOAD_CONST               1 (1)
              7 ROT_TWO
              8 LOAD_CONST               2 ('x')
             11 STORE_SUBSCR
             12 DUP_TOP
             13 LOAD_CONST               3 (2)
             16 ROT_TWO
             17 LOAD_CONST               4 ('y')
             20 STORE_SUBSCR

New disassembly:
              0 BUILD_MAP                0
              3 LOAD_CONST               1 (1)
              6 LOAD_CONST               2 ('x')
              9 STORE_MAP
             10 LOAD_CONST               3 (2)
             13 LOAD_CONST               4 ('y')

d8672aa8a4 Fix compile.c so that it records 0.0 and -0.0 as separate constants in a code 
object's co_consts tuple; add a test to show that the previous behavior (where
these two constants were "collapsed" into one) causes serious malfunctioning.

Note that ast.c still has a mix of tabs and spaces, because it
attempts to use four-space indents for more of the new code.

21997afb0c Fix bug #1565514, SystemError not raised on too many nested blocks. 
It seems like this should be a different error than SystemError, but
I don't have any great ideas and SystemError was raised in 2.4 and earlier.

Will backport.

82271f13e7 Fix for SF bug 1569998: break permitted inside try. 
The compiler was checking that there was something on the fblock
stack, but not that there was a loop on the stack.  Fixed that and
added a test for the specific syntax error.

Bug fix candidate.

4f096d9487 Patch #1542451: disallow continue anywhere under a finally 
I'm undecided if this should be backported to 2.5 or 2.5.1.
Armin suggested to wait (I'm of the same opinion).  Thomas W thinks
it's fine to go in 2.5.

84167d09cd Even though _Py_Mangle() isn't truly public anyone can call it and 
there was no verification that privateobj was a PyString.  If it wasn't
a string, this could have allowed a NULL pointer to creep in below and crash.

I wonder if this should be PyString_CheckExact?  Must identifiers be strings
or can they be subclasses?

0cbd805a10 Bug #1333982: string/number constants were inappropriately stored 
in the byte code and co_consts even if they were not used, ie
immediately popped off the stack.

4ffedadb10 Bug #1191458: tracing over for loops now produces a line event 
on each iteration.  I'm not positive this is the best way to handle
this.  I'm also not sure that there aren't other cases where
the lnotab is generated incorrectly.  It would be great if people
that use pdb or tracing could test heavily.

Also:
 * Remove dead/duplicated code that wasn't used/necessary
   because we already handled the docstring prior to entering the loop.
 * add some debugging code into the compiler (#if 0'd out).

da5b701aee Get rid of __context__, per the latest changes to PEP 343 and python-dev 
discussion.
There are two places of documentation that still mention __context__:
Doc/lib/libstdtypes.tex -- I wasn't quite sure how to rewrite that without
spending a whole lot of time thinking about it; and whatsnew, which Andrew
usually likes to change himself.

2c33fc77fe per Jeremy's email, remove the _WITH_CAST versions of macros. g++ 
still has errors from the casts of asdl_seq_GET to cmpop_ty, but
otherwise it's C++ clean.

7b782b61c5 more low-hanging fruit to make code compile under a C++ compiler. Not 
entirely happy with the two new VISIT macros in compile.c, but I
couldn't see a better approach.

ed40ea1159 Generate line number table entries for except handlers. 
Re-enable all the tests in test_trace.py except one.  Still not sure that these tests test what they used to test, but they pass.  One failing test seems to be caused by undocumented line number table behavior in Python 2.4.

f669436189 Um, I thought I'd already checked this in. 
Anyway, this is the changes to the with-statement
so that __exit__ must return a true value in order
for a pending exception to be ignored.
The PEP (343) is already updated.

5e9f1fa706 Generally inehrit codeflags that are in PyCF_MASK, instead of writing it out 
in multiple places. This makes compile()/eval()/etc also inherit the
absolute-import codeflag, like division and with-statement already were.
