[patch,wwwdocs] a new treegion branch webpage

This patch adds the treegion scheduling project to
wwwdocs/htdocs/svn.html.  It also includes project/sched-treegion.html, a
new file describing the project.

+ <h2><a name="intro">Introduction</a></h2>
+
+ <p>Instruction scheduling is one of the most important phases of
compilation
+ for high-performance processors. A compiler typically divides a program
into
+ multiple regions of code and then schedules each region. Many past efforts
+ have focused on linear regions such as traces and superblocks. The
linearity
+ of these regions can limit speculation, leading to underutilization of
+ processor resources, especially on wide-issue machines. A type of
non-linear
+ region called a treegion is implemented in this work. The formation and
+ scheduling of treegions takes into account multiple execution paths, and
the
+ larger scope of treegions allows more speculation, leading to higher
+ utilization and better performance.</p>
+
+ <p>The implementation currently resides on the branch.</p>
+
+ <h2><a name="contributing">Contributing</a></h2>
+
+ <p>Checkout the sched-treegion branch following the instructions found
in the
+ <a href="../svn.html">SVN documentation</a>.</p>
+
+ <p>When posting to the development lists, please mark messages and patches
+ with [sched-treegion] in the subject. The usual contribution and testing
