3a6b488265 Can't re-materialize mov r, imm in thumb since mov would clobber the condition code.

686756b11e Remove some non-sensical logic that prevented llvm-nm from working on any 
file other than one named "-".

e35e9d07b0 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.

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.

39861bcc6a 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.

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.

ebab693178 For PR1283: 
Change the llvm-gcc sanity check to look for "target datalayout" instead
of "implementation". The implementation keyword is no longer generated
by llvm or llvm-gcc.

1. Line out nested call of APInt::zext/trunc.
2. Make more use of APInt::getHighBitsSet/getLowBitsSet.
