Original commit message:
[interpreter] Remove TryInstallOptimizedCode
Removes the interrupt check and runtime call to TryInstallOptimizedCode
from the optimization marker checks (i.e. CompileLazy and
InterpreterEntryTrampoline). Instead, we rely on the other interrupt
sources (in particular stack checks at function entries and loop
headers) to install optimized code for us.
This will hopefully not cause regressions, as we have plenty of other
interrupt checks, but it may delay optimized code execution for
some function by one function call.
