Fix incorrect form test in SymbolFileDWARF
Summary:
We were checking whether an attribute is in block form by getting the block data pointer, which
was not correct as the pointer be null even if the attribute is in block form. Other places in
the file already use the correct test.
To make this work, I've needed to add DW_FORM_exprlock to the list of "block" forms, which seems
correct as that is how we are parsing it.

Fix DataExtractor::PeekData for zero length peeks
Summary:
The function was returning the null pointer for peeks of size zero, which seems like a sensible
thing to do, but is actually pretty easy to get bitten by that if you are extracting a variable
length field which happens to be of zero length and then doing pointer arithmetic on that (which
SymbolFileDWARF does, and ended up crashing in case of empty DW_AT_location).
This changes the function to return a null pointer only when it gets queried for data which is
outside of the range of the extractor, which is more c++-y, as one can still do reasonable things
with pointers to data of size zero (think, end() iterators).
I also add a test and fix some signedness warnings in the existing data extractor tests.

[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.

This is a compromise that still allows wrapping StringSwitch in other

StringSwitch cannot be copied or moved.
...but most importantly, it cannot be used well with 'auto', because
the inferred type is StringSwitch rather than the result type. This
is a problem because StringSwitch stores addresses of temporary
values rather than copying or moving the value into its own storage.
Changing this uncovered the bug in PassBuilder, also in this patch.
Clang doesn't seem to have any occurrences of the issue.

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.
