Simplify DIxxx:Verify to not call Verify on an operand. Instead, we use
DebugInfoFinder to list all MDNodes that should be a DIScope and all MDNodes
that should be a DIType and we will call Verify on those lists.

The original change was rolled back in r186627 because of test
failures on the big endian machine. I believe I fixed the issue
so re-submitting.

Summary:
This allows the clang driver to put MSVC compatible options in the same
enumerator space as its normal options but exclude them from normal
option parsing.
Also changes the standard ParseArgs() method to consider unknown
arguments with a leading slash as being inputs rather than flags.

Summary:
Dump optional data directory entries in the PE/COFF header, so that
we can test the output of LLD linker. This patch updates the test binary
file, but the source of the binary is the same. I just re-linked the file.
I don't know how the previous file was linked, but the previous file did
not have any data directory entries for some reason.

The plan is to use it for clang and lld.
Major behavior changes:
- We can now parse UTF-16 files that have a byte order mark.
- PR16209: Don't drop backslashes on the floor if they don't escape
anything.
The actual parsing loop was based on code from Clang's driver.cpp,
although it's been rewritten to track its state with control flow rather
than state variables.

We don't want cast and dyn_cast to work on temporaries. They don't extend
lifetime like a direct bind to a reference would, so they can introduce
hard to find bugs.
I added tests to make sure we don't regress this. Thanks to Eli Friedman for
noticing this and for his suggestions on how to test it.

it clear what we want to do. Unfortunately the conversion to
pointer operator fires now instead and chasing down all of the
conversions and making them explicit and handled is a large task
so add a FIXME with it.

This is to support parsing UTF16 response files in LLVM/lib/Option for
lld and clang.

llvm-ar is the only user of toWin32Time() (via setLastModificationAndAccessTime), and r186298 can be reverted.
It had been buggy since the initial commit.
FIXME: Could we rename {from|to}Win32Time as {from|to}Win32FILETIME in TimeValue?

No functionality change.
This is preparing to move response file parsing into lib/Option so it
can be shared between clang and lld. This change isn't just a
micro-optimization. Clang's driver uses a std::set<std::string> to
unique arguments while parsing response files, so this matches that.

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.

Address calculation for gather/scather in vectorized code can incur a
significant cost making vectorization unbeneficial. Add infrastructure to add
cost.
Tests and cost model for targets will be in follow-up commits.

This is a generic block implementation that works on more than machine blocks.
The C++ mode addition is a bonus due to the extra space provided.

Summary:
This patch adds explicit calling convention types for the Win64 and
System V/x86-64 ABIs. This allows code to override the default, and use
the Win64 convention on a target that wants to use SysV (and
vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU
attributes.
