[Ic-Processor] Let us know if an IC is in opt. or unopt. code.

Traditionally, we had a prefix for a function name of "~" for
unoptimized code and "*" for optimized code. Restore this prefix
in v8/tools/ic-processor. It's really cool to know if an IC was
called from optimized code (often a hint of poor performance!).
