Merge branch 'qfcc-cse'
...
qfcc now does local common subexpression elimination. It seems to work, but
is optional (default off): use -O to enable. Also, uninitialized variable
detection is finally back :)
The progs engine now has very basic valgrind-like functionality for
checking pointer accesses. Enable with pr_boundscheck 2

The usual -O :) (no numbers yet, though). Alternatively, -C [no-]optimize
may be used.

Add an option to dump frame files.
...
After running across a question about lists of animation frames and states,
I decided giving qfcc the ability to generate such lists might be a nice
distraction from the optimizer :) Works for both progs.src and separate
compilation. No frame file is generated if no macros have been created.

Calculate a node's successors and predecessors.

The dot graphs are a little odd (arrow heads on the wrong end of the
predecessor edges), but things seem to be correct.

Attach dags to statement blocks.

Now, if a dag is attached to a statement block, it will be included in the
flowgraph with that statement block.

Add an extended mode to qfcc.

Extended mode allows extra keywords (switch, for, etc) that are compatible
with v6 progs.

Output basic block flow diagrams to files.
...
The output can be controlled via --block-dot (not yet documented). The
files a named <sourcefile>.<function>.<stage>.dot. Currently, stage will be
one of "initial" (after expression to statement conversion), "thread"
(after jump threading), "dead" (after dead block removal), "final" (final
state before actual code emission).

Allow control of progdefs.h CRC writing.

CRC writing defaults to off for non-v6 progs, but on for v6 progs. The
--progdefs option forces CRC writing.

Add an option to prevent the use of default paths.
...
Despair has things locked down such that running qfcc during a build fails
due to lack of read access to /usr/local/lib. This is actually a good
thing as accidentally hitting old includes/libs (when a file gets deleted
in the tree) hides bugs. Thus, --no-default-paths to turn off default
search paths.

Optionally create *_[xyz] symbols for accessing vector components.
...
"vector-components" in code options controls this feature. The default is
off for advanced code and on for traditional code. Disabling
vector-components prevents the comonent names polluting the namespace and
reduces the number of globals needed for vector fields if the components
of that field are never used.
