[CMake] Support feeding DYLD_LIBRARY_PATH into archiver calls
OS X 10.11 has a feature named System Integrity Protection. The goal of the feature is to make system binaries immutable (even as root). One part of this is that protected binaries do not receive DYLD_* environment variables because the kernel scrubs them before process launch.
This causes problems for LTO bootstrap builds on Darwin that try to use the just-built libLTO with the host ar, ranlib, or libtool.
This patch addresses two problems.
(1) The tools themselves aren't protected binaries but the shim tools installed at / are, so we need to call xcrun -find to find libtool instead of using the one CMake finds.
(2) Some build tools (ninja and make) use /bin/sh to invoke their subprocesses. Since /bin/sh is a system binary, the kernel scrubs the DYLD envars from their environment. To work around this we need to set the environment variables as part of the archiver commands, so the envars are set by the shell process instead of on the shell process.

Next step along the way to getting good error messages for bad archives.
I consulted with Lang Hames on this work, and the goal was to add a bit
of "where" in the archive the error occurred along with what the error was.
So this step changes ArchiveMemberHeader into a class with a pointer
to the archive header and the parent archive. Which allows the methods
in the ArchiveMemberHeader to determine which member the header is
for to include that information in the error message.
For this first step the "where" is just the offset to the member in the
archive. The next step will be a new method on ArchiveMemberHeader
to get the full name, if possible, to be use in the error message. Which
will now be possible as ArchiveMemberHeader contains a pointer to
the Archive with its string table and its size, etc. so the full name can
be determined from the header if it is valid.
Also this change adds the missing checks the archive header is actually
contained in the buffer and is not truncated, as well as if the terminating
characters are correct in the header.
And changes one error message in Archive::Child::getNext() where the
name or offset to member is now added.

With this patch enabled CMAKE_C_FLAGS is duplicated on all C sources, and applied to ASM sources, which is not ideal.
I sent an email about this to llvm-commits on the commit thread. I suspect the problem the patch author was actually seeing is that CMAKE_C_FLAGS isn't applied to ASM files, and the builtins library has quite a few of those. The correct solution there is to specify CMAKE_ASM_FLAGS with whatever flags need to be passed to the compiler when compiling ASM files.

This check verifies if buffer type and MPI (Message Passing Interface)
datatype pairs match. All MPI datatypes defined by the MPI standard (3.1)
are verified by this check. User defined typedefs, custom MPI datatypes and
null pointer constants are skipped, in the course of verification.

Apply all necessary tilings and interchangings to get a macro-kernel
This is the second patch to apply the BLIS matmul optimization pattern
on matmul kernels
(http://www.cs.utexas.edu/users/flame/pubs/TOMS-BLIS-Analytical.pdf).
BLIS implements gemm as three nested loops around a macro-kernel, plus
two packing routines. The macro-kernel is implemented in terms
of two additional loops around a micro-kernel. The micro-kernel
is a loop around a rank-1 (i.e., outer product) update. In this change
we create the BLIS macro-kernel by applying a combination of tiling
and interchanging. In subsequent changes we will implement the packing
transformation.

[libunwind][ARM] Add support for Thumb1 targets
The Thumb1 version of the code for saving and restoring the unwind
context has a few bugs which prevent it from working:
* It uses the STM instruction without writeback, which is not valid for Thumb1
(It was introduced in Thumb2).
* It only saves/restores the low 8 registers, the sp and the lr, so if a
program uses r8-r12 they will not be correctly restored when throwing an
exception.
There aren't currently any Thumb1 build-bots to test this, but we have
been successfully running the libc++abi and libc++ test suites on
Cortex-M0 models, as well as some other test suites that use C++
exceptions on a downstream version of libunwind with this patch applied.
