48a55f7e74 Revert "Recommend turning "hot" higher-order calls into first-order calls." 
This reverts commit bb0c20ce6eff2112a25eb1f98d394b36da0128f8.

Was never useful in practice.

c66654e9c8 Allow producing multiple inliner report entries per function. 
This also allows reporting one function while traversing another.

fa01a5304a Recognize "interesting" call sites. 
These are call sites where one of the callees accounts for a large portion
of the total time of its caller.

When such call sites are considered inlining failures, we can refine
recommendations.

The concept of interesting call site is also useful as a building block
for higher-level patterns.

c8d3aea6dd Rethink profiler integration. 
Requires the program to manually call the profiler. This dumps the results in
a separate file.

18e4cbbb40 First stab at hooking the profiler up to OC. 
Profiling is done from inside the eval, to minimize noise.

Use samplers directly, to get access to the profiler's data structures.

ac58c45477 Disable optimization of mixed-mode arithmetic that may involve exact 0. 
Exact 0 turns out to also be a corner case for addition.

At this point, mixed-mode optimizations pretty much only apply for mixes
of floats and literal non-zero non-floats.
