Seth Brenith ab52d52527 Avoid overflow when profiling builtins 
The basic block instrumentation currently uses 32-bit integers, which
could overflow during a long profiling session. I considered upgrading
them to 64-bit integers, but generating the correct instrumentation code
for various architectures would be rather non-trivial. Instead, this
change uses 64-bit floating-point values, which are simple and also have
the nice behavior that they saturate rather than overflowing.
