Nuno Lopes eeef4d29d6 remove the optimization for 0-byte allocations 
I wasn't able to trigger with any SMT or API benchmark
Removing it ensures the function never returns null and enables further optimizations.
I get an amazing avg speedup of 0.9%

Alex Horn c8a123b7dd Disable a few rule transformations 
For this prototype, we need to disable three rule transformations,
namely coi_filter, similarity_compressor, rule_inliner. But
disabling the inliner causes problems with the tracer in the
datalog interpreter. Since a new proprocessor is underway, we
skip the problematic trace outputs for now.
