make getBase() return a const-correct pointer.

f2309c208a Remove MappedFile support for mapping files for write and exec 
and shared.  This complicates the design, is not used, and probably
doesn't even work.

c3d03d3f10 cleanup the MappedFile API and comments. This removes and updates 
tons of out of date comments (really nothing throws here!) and fixes
some other fairly glaring issues: "size" used to return the size of 
the file *and* change it, depending on how you called it.

479c8ef76d Specialize FORCE_DEFINING_FILE_TO_BE_LINKED using a GCC trick 
to avoid using constructor calls for static objects. This reduces
the number of objects requiring static constructors in a typical
LLVM build by around 20%.

47526c4a42 Remove host endianness info from TargetData and

Instead of getting the endianness from configure,
calculate it directly.

caf5a6cbd7 Teach sys::Path how to recognize different kinds of object files for ELF 
and Mach-O systems. Additionally, correct the Mach-O logic code to look at
byte 12 not byte 15. Hopefully this fixes the llvm-ld warning on Darwin.

4269ae1274 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.

d0eb672f1e 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.

fc67ef7cfe For PR789: 
* Add a method: bool isAbsolute() const, which determines if the path name
  is absolute or not.
* Implement caching of file status information in the Path object. Allow it
  to be updated forcefully or lazily re-fetched from the cached value.

e2b7b29a82 For PR797: 
Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:
