dlmalloc benchmark

Attached is dlmalloc compiled to JS. Results:

m-c -m -j -p      9.273
jm  -m -j -p -n   4.139
v8                2.739

TI is much better than current spidermonkey, but still significantly behind v8.

I think this is fairly important since dlmalloc is real-world code, not an artificial microbenchmark. One difference from microbenchmarks is the size of the code. In bug 678939 Jan mentioned that not compiling IFEQX might be a factor in such scripts, and that should be now done on jm but not m-c, which can potentially explain some of the slowness on m-c (but not that jm is still slower than v8).
