I think the standard name is "adaptive optimization":

http://en.wikipedia.org/wiki/Adaptive_optimization

"Adaptive optimization is a technique in computer science that performs 
dynamic recompilation of portions of a program based on the current 
execution profile."

"Consider a hypothetical banking application that handles transactions 
one after another. These transactions may be checks, deposits, and a 
large number of more obscure transactions. When the program executes, 
the actual data may consist of clearing tens of thousands of checks 
without processing a single deposit and without processing a single 
check with a fraudulent account number. An adaptive optimizer would 
compile assembly code to optimize for this common case. If the system 
then started processing tens of thousands of deposits instead, the 
adaptive optimizer would recompile the assembly code to optimize the new 
common case. This optimization may include inlining code or moving error 
processing code to secondary cache."
