I don't really get the obsession w/ compiler performance. At the end of the day you are trading performance optimizations (inlining, dead code elimination, partial evaluation, etc) for compile times. If you want fast compile times then use a compiler w/ no optimization passes, done. The compile times are now linear w/ respect to lines of code & there is provably no further improvement you can make on that b/c any further passes will add linear or superlinear amount of overhead depending on the complexity of the optimization.
