* Move implementation of sys::PreventCoreFiles function to this file from
  the now defunct SysConfig abstraction.

7da5e588d4 For PR351:
SysConf abstraction was pointless because it had a single function in it that
pertained only to the current process. So merge it into the Process abstraction
and remove the files completely.

9d3a8ad836 Fix a file overwrite bug in llvm-ar introduced by changes to
createTemporaryFile semantics where it doesn't create a fully unique name
if the basename doesn't exist. This functionality is now optionally
provided by the boolean reuse_current parameter to createTemporaryFile and
makeUnique. The default values differ because of the way these functions
are used in LLVM.

5a18b63eb5 For PR351:
Implement three new functions to allow setting access/permission bits on
the file referenced by a path. The makeReadable and makeExecutable methods
replace the FileUtilities MakeFileReadable and MakeFileExecutable
functions. The makeWritable function is new and provided for consistency
since Path has a writable() method.

fea77c07f6 Add in some methods for use by the JIT. LoadLibraryPermanently brings the
library into the address space permanently. SearchForAddressOfSymbol looks
in all previously permanently loaded libraries and any currently open
libraries for a symbol, instead of just one library like GetAddressOfSymbol

* Clean up the StatusInfo constructor to construct all members and give

  content is sorted.

da2e8b9943 First version of the MappedFile abstraction for operating system idependent
mapping of files. This first version uses mmap where its available. The
