Richard:
I'm sorry it's taking so long to test these patches, but it's not
trivial to figure out what to measure. So as a first pass I've
collected compile time and files sizes for the programs in the
Gambit test suite at
http://www.math.purdue.edu/~lucier/gcse-test.html
Basically, with your patches, all the compile times without gcse are
lower than before; with gcse, the compile times can be significantly
lower (2.95 seconds versus 118.84 seconds in one extreme case).
There was one anomalous result where compile times increased both
with and without gcse with your patches.
I have no idea yet about how the patches affect performance. That's next ...
