Since GNU ar 2.31, the 't' operation prints member offsets beside file
names if the 'O' modifier is specified. 'O' is ignored for thin
archives.

Summary:
The POSIX spec says:
```
If the −t option is used with the −v option, the standard output format shall be:
"%s %u/%u %u %s %d %d:%d %d %s\n", <member mode>, <user ID>,
<group ID>, <number of bytes in member>,
<abbreviated month>, <day-of-month>, <hour>,
<minute>, <year>, <file>
where:
...
<abbreviated month>
Equivalent to the format of the %b conversion specification format in date.
<day-of-month>
Equivalent to the format of the %e conversion specification format in date.
<hour> Equivalent to the format of the %H conversion specification format in date.
<minute> Equivalent to the format of the %M conversion specification format in date.
<year> Equivalent to the format of the %Y conversion specification format in date.
```
This actually used to be the format printed by llvm-ar. It was apparently accidentally changed (see r207385 followed by comments in r207387). This makes it conform to GNU ar for easier replacement.

This is important for thin archives.

It is pretty unambiguous how to interpret it and gnu ar accepts it too.

This is just sufficient for 'ar t' to work.

odd to have the output of 'llvm-ar tv' depend on the format of
TimeValue::str(), but that's what we have today. If anyone needs the
output to remain compatible with GNU ar or old versions of llvm-ar, just
shout and I'll switch the code to manually format its times.
Note that there isn't a portable format -- Mac and GNU have different
formats at least (thanks Rafael!) so...

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.

While at it, use strftime on Unix too and use the thread safe versions
of localtime.
