Reid Spencer ee7eaa25cf For PR801: 
Refactor the Graph writing code to use a common implementation which is
now in lib/Support/GraphWriter.cpp. This completes the PR.

Patch by Anton Korobeynikov. Thanks, Anton!

Chris Lattner 63a46cee87 Signficantly speed up printing by not emitting the same file twice with 
different names.  Large SCC's tend to be big, so this saves a lot of time.

Chris Lattner a1b39fa5ad * Make some methods more const correct. 
* Change the FunctionCalls and AuxFunctionCalls vectors into std::lists.
  This makes many operations on these lists much more natural, and avoids
  *exteremely* expensive copying of DSCallSites (e.g. moving nodes around
  between lists, erasing a node from not the end of the vector, etc).

With a profile build of analyze, this speeds up BU DS from 25.14s to
12.59s on 176.gcc.  I expect that it would help TD even more, but I don't
have data for it.

This effectively eliminates removeIdenticalCalls and children from the
profile, going from 6.53 to 0.27s.

Brian Gaeke e330adf842 Move the stuff that fixes the size, orientation & fonts of graphs to 
the debugging functions that call "dot". These fixed settings have
various problems: for example, the fixed size that is set in the graph
traits classes is not appropriate for turning the dot file into a PNG,
and if TrueType font rendering is being used, the 'Courier' TrueType font
may not be installed. It seems easy enough to specify these things on the
command line, anyhow.
