More-accurate Gnome-terminal profiling

[Travis Reitter <treitter-dev netdrain com>]

A zombifying week after finally gathering this new data, here is a more
accurate performance view of gnome-terminal, uxterm, and xterm:

	(same URL as before)

Changes in this version:
	* X.org recompiled without custom module loader
	* -O2 flag used to be a little more realistic to real usage
	* Included data for Kmaraas' VTE patch.

Kjartan's patch may make things slightly better (throughput). Other
metrics didn't really change. It needs a little more study to know for
sure if it's significant, but it doesn't appear to hurt anything.

More feedback would be great, especially if anyone notices any in the
gnome-terminal profiling that we should start chipping away at.
