944f684ce6 Allow multiple context managers in one with statement, as proposed 
in http://codereview.appspot.com/53094 and accepted by Guido.

The construct is transformed into multiple With AST nodes so that
there should be no problems with the semantics.

68d6852006 Backport r69961 to trunk, replacing JUMP_IF_{TRUE,FALSE} with 
POP_JUMP_IF_{TRUE,FALSE} and JUMP_IF_{TRUE,FALSE}_OR_POP. This avoids executing
a POP_TOP on each conditional and sometimes allows the peephole optimizer to
skip a JUMP_ABSOLUTE entirely. It speeds up list comprehensions significantly.

92c3b2190b Issue #999042: The Python compiler now handles explict global statements 
correctly (should be assigned using STORE_GLOBAL opcode).  This was done by
having the system table differentiate between explict and implicit globals.

4db626f95d Overhaul Lib/compiler block ordering. The previous code was filled with 
hacks.  The new code is based on issue #2472 posted by Antoine Pitrou.  I
did some further cleanups of the pyassem code and optimized the block
ordering pass.

06ded09d40 Fix the 'compiler' package to generate correct code for MAKE_CLOSURE. 
In the 2.5 development cycle, MAKE_CLOSURE as changed to take free
variables as a tuple rather than as individual items on the stack.
Closes patch #1534084.

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.

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.

eaed39f303 Hopefully this removes all vestiges of CO_GENERATOR_ALLOWED that can 
be removed in 2.x.

fa0cf4f3ae Add support for absolute/relative imports and if/else expressions: 
- regenerate ast.py
 - add future flags for absolute-import and with-statement so they
   (hopefully) properly get set in code-object flags
 - try out if/else expressions in actual code for the hell of it.

Seems to generate the same kind of bytecode as the normal compiler.

5bde08dba3 Fix failure of test_compiler.py when compiling test_contextlib.py. 
The culprit was an expression-less yield -- the first apparently in
the standard library.  I added a unit test for this.
Also removed the hack to force compilation of test_with.py.

Sigh -- we really should have one place for all opcode metadata.

c2e20744b2 PEP 343 -- the with-statement. 
This was started by Mike Bland and completed by Guido
(with help from Neal).

This still needs a __future__ statement added;
Thomas is working on Michael's patch for that aspect.

There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).
