9cfbdad631 Replace archive members in the old position. 
This matches gnu archive behavior and since archive member order can change
which member is used, not changing the order on replacement looks like the
right thing to do.

This patch also refactors the logic for which archive member to keep and
whether to move it to a helper function (computeInsertAction). The
nesting in computeNewArchiveMembers was getting a bit confusing.

c2acfa8f64 Handle replacement into a position past the original member. 
We were incorrectly computing where to insert a member if it was replacing
a previous member that was before the insert point.

2a9326a78f Add a wrapper for open. 
This centralizes the handling of O_BINARY and opens the way for hiding more
differences (like how open behaves with directories).

25c838d63e Remember that we have a null terminated string. 
This is a micro optimization. Instead of going char*->StringRef->Twine->char*,
go char*->Twine->char* and avoid having to copy the filename on the stack.

Looks like on mingw we get bogus last modification times on directories.

6c3ac6c001 Change llvm-ar to use lib/Object. 
This fixes two bugs is lib/Object that the use in llvm-ar found:
* In OS X created archives, the name can be padded with nulls. Strip them.
* In the constructor, remember the first non special member and use that in
  begin_children. This makes sure we skip all special members, not just the
  first one.

The change to llvm-ar itself consist of
* Using lib/Object for reading archives instead of ArchiveReader.cpp.
* Writing the modified archive directly, instead of creating an in memory
  representation.

The old Archive library was way more general than what is needed, as can
be seen by the diffstat of this patch.

Having llvm-ar using lib/Object now opens the way for creating regular symbol
tables for both native objects and bitcode files so that we can use those
archives for LTO.

6654d0be49 Remove support for truncating names in archives. 
* All systems we support have some form of long name support.
* The options has different names and semantics in different implementations
  ('f' on gnu, 'T' on OS X), which makes it unlikely it is normally used on
  build systems.
* It was completely untested.

1741a5940a Fixes problem when calling llvm-ar from an unmodifiable directory. 
This fixes a regression introduced by r185726: the new call to get
a unique file does not prepend the system temporary directory, so
we need to anchor on the file that the temporary file gets moved
to to ensure we're on the same file system.

66da97e093 Add a createUniqueFile function and switch llvm's users of unique_file. 
This function is complementary to createTemporaryFile. It handles the case were
the unique file is *not* temporary: we will rename it in the end. Since we
will rename it, the file has to be in the same filesystem as the final
destination and we don't prepend the system temporary directory.

This has a small semantic difference from unique_file: the default mode is 0666.
This matches the behavior of most unix tools. For example, with this change
lld now produces files with the same permissions as ld. I will add a test
of this change when I port clang over to createUniqueFile (next commit).

fdd1dfd455 Don't treat bitcode files specially in llvm-ar. 
We really want bitcode files to behave as regular object files in archives, so
we don't need to track that a member is bitcode.
