Update ModuleSummaryIndexBitcodeReader::makeCallList reserve amount (#95461)
Tighten the reserve() to `Record.size() / 2` instead of `Record.size()`
in the HasProfile/HasRelBF cases. For the uncommon old profile format
cases we leave it as is, but those should be rare and not worth
optimizing.
This reduces peak memory during ThinLTO indexing by ~3% in one example.
Alternatively, we could make the branching for reserve more complex and
try to cover every case.
