a145c6d766 Remove some non-sensical logic that prevented llvm-nm from working on any 
file other than one named "-".

1ea733db9d Use the stat information in the Path object, if it is already obtained. This 
avoids a call to ::fstat by MappedFile when the file size information was
already obtained by the Path object.

8475ec068c For PR789: 
Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

cb2df95c88 checkpoint -> implementation. This really needs to just drop the need for 
a keyword by having the assembler check for incomplete types and values
upon end-of-file.

4031befb62 Add a uniqueID field to the FileStatus structure for Paths. This will map 
to the inode number on Unix and something far less unique on Windows. The
windows case needs to be improved.
