SF bug 430991: wrong co_lnotab
Armin Rigo pointed out that the way the line-# table got built didn't work
for lines generating more than 255 bytes of bytecode. Fixed as he
suggested, plus corresponding changes to pyassem.py, plus added some long
overdue docs about this subtle table to compile.c.
Always emit a SET_LINENO 0 at the beginning of the module. The
builtin compiler does this, and it's much easier to compare bytecode
generated by the two compilers if they both do.
Move the SET_LINENO inside the FOR_LOOP block for list
comprehensions. Also for compat. with builtin compiler.
Fix annoying bugs in flow graph layout code. In some cases the
implicit control transfers weren't honored. In other cases,
JUMP_FORWARD instructions jumped backwards.
Remove unused arg from nextBlock().
pycodegen.py
Add optional force kwarg to set_lineno() that will emit a
SET_LINENO even if it is the same as the previous lineno.
Use explicit LOAD_FAST and STORE_FAST to access list comp implicit
variables. (The symbol table doesn't know about them.)
