Commit e2ca7cb504a84b7a64c670455eb5e66e9cf0ecff by l.lunak
make ConstString allocate memory in non-tiny chunks
BumpPtrAllocator allocates in 4KiB chunks, which with any larger project
is going to result in a large number of allocations. Increasing
allocation size this way can save 10%-20% of symbol load time for a huge
C++ project with correctly built debuginfo.
