First version of the MappedFile abstraction for operating system idependent
mapping of files. This first version uses mmap where its available. The class needs to implement an alternate mechanism based on malloc'd memory and file reading/writing for platforms without virtual memory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16649 91177308-0d34-0410-b5e6-96231b3b80d8
