Stop looking for 'time between passes' for old compiler performance graphs

[trivial, not reviewed] 

With r23519 the time that was previously reported in 'time between passes' is
now tacked on the passes themselves. Removing it from the perfkeys and .graph
files for these older compiler performance tests.

Look for 'total time: ' instead of 'total :' for compiler performance keys

[trivial, not reviewed] 

'total time' was changed to 'total' with r23519. I updated most of the compiler
performance .dat files to reflect this (and due to this and other changes
chap08 and chap12 were blown away.) However I forgot about the compiler
performance tests that exist in regular performance testing.  Just reverting
'total' back to 'total time' is easier than changing ~50 .dat files and
rerunning releaseOverRelease performance results. I'll update the .dat files
for chap01 again and blow away chap08 and chap12 again since they only have a
day's worth of data. 

This patch just reverts the perfkeys to look for 'total time', as well as the
prediff for filtering out the extra print-passes info and reverts the graph
keys for the 'total time' graphs.

Minor fixes in syncing perf graphs and saving .dat files

[trivial, not reviewed]

While I was looking into the errors syncing to sourceforge today I noticed that
we don't close the log file if the syncPerfGraphs script returns because a
SUCCESS file wasn't found. Also removed trailing whitespace from syncPerfGraphs
while I was in there. In nightly, the call to add svn ignore to non-dat
files didn't cd to the svnPerf directory first.
