Fix raw_fd_ostream::write_impl hang due to an infinite loop with large output On windows when raw_fd_ostream::write_impl calls write, a 32 bit input is required for character count. As a variable with size_t is used for this argument, on x64 integral demotion occurs. In the case of large files an infinite loop follows. See: https://bugs.llvm.org/show_bug.cgi?id=37926 This fix allows the output of files larger than the previous int32 limit.
