Before this patch we would strdup each argument. If one was a response file,
we would replace it with the response file contents, leaking the original
strdup result.

We now don't strdup the originals and let StringSaver free any memory it
allocated. This also saves a bit of malloc traffic when response files are
not used.

Leak found by the valgrind build bot.

With this change each transform now register a factory. The factories are
registered using an llvm::Registry which makes them available globally.

The Binary constructor takes ownership of the memory buffer. This is a fairly
unfortunate interface, but for now make createObjectFile consistent with it
by also deleting the buffer if it fails.

Fixes a leak in llvm-ar found by the valgrind bots.

This is far from implementing all the rules given by

The important new feature is the support for styles that don't have a
column limit. For such styles, clang-format will (at the moment) simply
respect the input's formatting decisions within statements.

I'm starting to commit KNL backend. I'll push patches one-by-one. This patch includes support for the extended register set XMM16-31, YMM16-31, ZMM0-31.

pending speculation for a phi node. The problem here is that we were
using growth of the specluation set as an indicator of whether
speculation would occur, and if the phi node is already in the set we
don't see it grow. This is a symptom of the fact that this signal is
a total hack.

Unfortunately, I couldn't really come up with a non-hacky way of
signaling that promotion remains valid *after* speculation occurs, such
that we only speculate when all else looks good for promotion. In the
end, I went with at least a much more explicit approach of doing the
work of queuing inside the phi and select processing and setting
a preposterously named flag to convey that we're in the special state of
requiring speculating before promotion.

Thanks to Richard Trieu and Nick Lewycky for the excellent work reducing
a testcase for this from a pretty giant, nasty assert in a big
application. =] The testcase was excellent.

    Similar to ARM change r182800, dynamic linker will read bits/addends from
    the original object rather than from the object that might have been patched
    previously. For the purpose of relocations for MCJIT stubs on MIPS, we
    internally use otherwise unused MIPS relocations.
    
    The change also enables MCJIT unit tests for MIPS (EL/BE), and the following
    two tests now pass:
    
    - MCJITTest.return_global and
    - MCJITTest.multiple_functions.
    
    These issues have been tracked as Bug 16250.

These are really the same address space in hardware.  The only
difference is that CONSTANT_ADDRESS uses a special cache for faster
access.  When we are unable to use the constant kcache for some reason
(e.g. smaller types or lack of indirect addressing) then the instruction
selector must use GLOBAL_ADDRESS loads instead.
