createRandomIndex was using the global RNG, which locks on every call
It was also using twice as many random numbers as necessary and doing
a float division in every iteration of the inner loop.
BenchmarkDecodeIndex was using too short an input, especially for a
parallel version. (It may now be using one that is a bit large.)

repository/master_index: Optimize Index.Lookup()
...
When looking up a blob in the master index, with several
indexes present in the master index, a significant amount of time
is spent generating errors for each failed lookup. However, these
errors are often used to check if a blob is present, but the contents
are not inspected making the overhead of the error not useful.
Instead, change Index.Lookup (and Index.LookupSize) to instead return
a boolean denoting if the blob was found instead of an error. Also change
all the calls to these functions to handle the new function signature.
