Reid Kleckner 11da004ac1 On Windows, autolink advapi32 from Path.inc for CryptAcquireContextW 
This allows llvm-tblgen to link successfully when compiling with clang.

Both MSBuild and CMake will automatically add advapi32 as part of a set
of other dlls comprising the win32 API to the link line, but CMake
doesn't do that when compiling with clang.  Until someone adds that info
to cmake upstream, this seems like a reasonable work around.

Rafael Espindola 107b74c6c3 Fix windows' implementation of status when a file doesn't exist. 
The unix one was returning no_such_file_or_directory, but the windows one
was return success.

Update the one one caller that was depending on the old behavior.

Rafael Espindola 7f822a9306 Include st_dev to make the result of getUniqueID actually unique. 
This will let us use getUniqueID instead of st_dev directly on clang.

Rafael Espindola 67080cec25 Split openFileForWrite into windows and unix versions. 
It is similar to 186511, but for creating files for writing.

Rafael Espindola 81177c5dac Small improvement to the use of GetFileType: 
* assert that the return value is one of the documented values on msdn.
* on FILE_TYPE_UNKNOWN, check GetLastError.

Unfortunately I can't think of a way to get a FILE_TYPE_UNKNOWN on a test.

NAKAMURA Takumi 8b01da4bd8 Windows/Path.inc: Introduce file_type::character_file and file_type::fifo_file in sys::fs::getStatus(HANDLE). 
It fixes llvm/test/Other/close-stderr.ll on msys.

FIXME: Provide unittests.

Rafael Espindola 16431fe7a7 Add FILE_SHARE_WRITE to openFileForRead. 
This should fix the windows bots. It looks like the failing tests are of the
form

prog1 > file
prog2 file

and prog2 fails trying to read the file. The best fix would probably be to close
stdout/stderr in prog1, but it was not the intention of 186511 to change this,
so just restore the old behavior for now.

Rafael Espindola a0d9b6b693 Split openFileForRead into Windows and Unix versions. 
This has some advantages:

* Lets us use native, utf16 windows functions.
* Easy to produce good errors on windows about trying to use a
directory when we want a file.
* Simplifies the unix version a bit.

Rafael Espindola 9da91a0e03 Instead friending status, provide windows and posix constructors to file_status. 
This opens the way of having static helpers in the .inc files that can
construct a file_status.

Rafael Espindola 4d08d8bada 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.

Rafael Espindola e79a87226a 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.

Rafael Espindola 158d537c5a 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?
