ac2de33d2a Use status to implement file_size. 
The status function is already using a syscall that returns the file size.
Remember it and implement file_size as a simple wrapper.

No functionally change, but clients that already use status now can avoid
calling file_size.

8e7294f995 Improvements to unique_file and createUniqueDirectory. 
* Don't try to create parent directories in unique_file. It had two problem:
   * It violates the contract that it is atomic. If the directory creation
     success and the file creation fails, we would return an error but the
     file system was modified.
   * When creating a temporary file clang would have to first check if the
     parent directory existed or not to avoid creating one when it was not
     supposed to.

* More efficient implementations of createUniqueDirectory and the unique_file
  that produces only the file name. Now all 3 just call into a static
  function passing what they want (name, file or directory).

Clang also has to be updated, so tests might fail if a bot picks up this commit
and not the corresponding clang one.

9e89fe77ce Add GetCurrentDirectory back. 
It looks like clang-tools-extra/unittests/cpp11-migrate/TransformTest.cpp
depends on the behaviour of the old one on Windows. Maybe a difference
between GetCurrentDirectoryA and GetCurrentDirectoryW?

bec3ce0cb5 The assumption that /proc/self/exe always exists is incorrect. 
For example, under a Linux chroot, /proc/ might not be mounted.
Therefor, we test if this file exist. If it is the case, use it (the current
behavior). Otherwise, we fall back to the detection used by *BSD.

The issue has been reported initially on the Debian bug tracker:
http://bugs.debian.org/674588

3c036e520e Teach Path::GetCurrentDirectory to use $PWD, to support users who like to do 
screwy things by setting PWD != getcwd(). For example, some developers I know
will use this to control the value in gcc's DW_AT_comp_dir value in debug
output. With this patch, that trick will now work on clang too.

The only other effect of this change is that the static analysis will now
respect $PWD when reporting the directory of the files in its HTML output. I
think that's fine.
