George Rimar f91f0b0af7 [Support/TarWriter] - Don't allow TarWriter to add the same file more than once.
This is for PR35460.

Currently when LLD adds files to TarWriter it may pass the same file
multiple times. For example it happens for clang reproduce file which specifies
archive (.a) files more than once in command line. 
Patch makes TarWriter to ignore files with the same path, so it will
add only the first one to archive.

Rui Ueyama 283f56ac03 Fix off-by-one error in TarWriter.
The tar format originally supported up to 99 byte filename. The two
extensions are proposed later: Ustar or PAX.

In the UStar extension, a pathanme is split at a '/' and its "prefix"
and "suffix" are stored in different locations in the tar header. Since
"prefix" can be up to 155 byte, it can represent up to 254 byte
filename (but exact limit depends on the location of '/' character in
a pathname.)

Our TarWriter first attempt to use UStar extension and then fallback to
PAX extension.

But there's a bug in UStar header creation. "Suffix" part must be a NUL-
terminated string, but we didn't handle it correctly. As a result, if
your filename just 100 characters long, the last character was droppped.

This patch fixes the issue.

Chandler Carruth 9a67b07398 Re-sort #include lines for unittests. This uses a slightly modified
clang-format (https://reviews.llvm.org/D33932) to keep primary headers
at the top and handle new utility headers like 'gmock' consistently with
other utility headers.

No other change was made. I did no manual edits, all of this is
clang-format.

This should allow other changes to have more clear and focused diffs,
and is especially motivated by moving some headers into more focused
libraries.

Rui Ueyama e9d17545bc TarWriter: Fix a bug in Ustar header.
If we split a filename into `Name` and `Prefix`, `Prefix` is at most
145 bytes. We had a bug that didn't split a path correctly. This bug
was pointed out by Rafael in the post commit review.

This patch adds a unit test for TarWriter to verify the fix.
