6d500da3cc Revert "[ELF] Order DT_NEEDED entries by command line order."
This reverts commit r204291 because it broke buildbots.

bc6b52e68e Move RoundTrip tests behind LLVM_RUN_ROUNDTRIP_TEST env flag.
If the environment variable is defined and not empty, RoundTrip tests
are run. The reason to move the tests behind the flag is because they
are too slow to enable by default.

LLD linking time on llvm-tblgen improved from 2m7s to 2.3s. About 60x
faster now in this case.

5f56e9d6cb [PECOFF] Fix parallel read bug.
InputElement::parse() may recursively call WinLinkDriver::parse() to handle
.drectve section contents, and if /defaultlib option exists in the section,
the driver will mutate the input graph to add a new input file to the graph.
So the access to input graph needs to be protected with mutext.

aca3c7c6f4 [PECOFF] Fix link order.
LLD fails to link symbol "_main" if the symbol is in a library file and
the library file is given as a bare argument (i.e. not with /defaultlib
option). It's because library files given as bare arguments are processed
before other libraries given with /defaultlib, so when Linker finds msvcrtd
needs a definition for "_main", the file providing the main function has
already been processed and skipped. Linker don't revisit libraries if it's
not given with /defaultlib.

To fix it this patch change the way of command line handling; files end with
".lib" are treated as if they are given with /defaultlib. I don't believe
it's 100% correct behavior but it's better than before.

13c70b6d4b Replace OwningPtr with std::unique_ptr.
This results in some simplifications to the code where an OwningPtr had to
be used with the previous api and then ownership moved to a unique_ptr for

An object whose machine type header value is unknown looks a bit odd but
is valid. If an object contains only machine-type-independent data, you
can leave the type field unspecified. Some files in oldname.lib are such
object files.
