101771ba4d For mips64 switch statements in subroutines could generate
within the codegen EK_GPRel64BlockAddress. This was not 
supported for direct object output and resulted in an assertion.

This change adds support for EK_GPRel64BlockAddress for 
direct object.

One fallout from this is to turn on rela relocations 
for mips64 to match gas.

cb1f68d7c8 Initialize SelectionDAGBuilder's Context in 'init', not in its constructor. The
SelectionDAG's 'init' has not been called when the SelectionDAGBuilder is
constructed (in SelectionDAGISel's constructor), so this was previously always
initialized with 0.

97defc37d6 Fix misaligned access in MachO object file reader: despite containing an
int64_t, Symbol64TableEntry is actually only stored with 4-byte alignment
within the file.

The usage of #pragma pack here is copied from the corresponding code in
Support/Endian.h, so shouldn't introduce any new portability problems.

19b1d84aaf Ignore the documentation-suggested location for compile_commands.json
According to http://clang.llvm.org/docs/HowToSetupToolingForLLVM.html
it's suggested that compile_commands.json in the root of the LLVM source tree
should be a symlink to the json file produced by your build system of choice.

So here's a patch so it doesn't turn up in git status, etc.

79c78de378 Remove unnecessary cast that was also unnecessarily casting away constness.
Even looking at the revision history I couldn't quite piece together why this
cast was ever written in the first place, but I assume it was because of some
change in the inheritance, perhaps this function was reimplemented in a
derived type & this caller was meant to get the base version (& it wasn't
virtual)?

91fcb7f420 PVS-Studio noticed that EmitVBR64 would perform undefined behaviour if the
number of bits was bigger than 32.  I checked every use of this function
that I could find and it looks like the maximum number of bits is 32, so I've
added an assertion checking this property, and a type cast to (hopefully) stop
PVS-Studio from warning about this in the future.

ec68f552f2 Port the global copy optimization from the SROA pass to InstCombine.
This optimization is really just replacing allocas wholesale with
globals, there is no scalarization.

The underlying motivation for this patch is to simplify the SROA pass
and focus it on splitting and promoting allocas.

990ca5517f Fix a quadratic algorithm in MachineBranchProbabilityInfo.
The getSumForBlock function was quadratic in the number of successors
because getSuccWeight would perform a linear search for an already known
iterator.

This patch was originally committed as r161460, but reverted again
because of assertion failures. Now that duplicate Machine CFG edges have
been eliminated, this works properly.

single CFG edge.

2c5a960b0e Clarify that duplicate edges are not allowed in the Machine CFG.
LLVM IR has labeled duplicate CFG edges, but since Machine CFG edges
don't have labels, it doesn't make sense to allow duplicates. There is
no way of telling what the edges mean.

Duplicate CFG edges cause confusion when dealing with edge weights. It
seems that code producing duplicate CFG edges usually does the wrong
thing with edge weights.

df2598871e enable cross compilation with cmake
This patch allows us to use cmake to specify a cross compiler: target different
than host. In particular, it moves LLVM_DEFAULT_TARGET_TRIPLE and TARGET_TRIPLE
variables from cmake/config-ix.cmake to the toplevel CMakeLists.txt to make them
available at configure time.

Here is the command line that I have used to test my patches to create a Hexagon
cross compiler hosted on x86:

$ cmake -G Ninja -D LLVM_TARGETS_TO_BUILD:STRING=Hexagon -D TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_DEFAULT_TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_TARGET_ARCH:STRING=hexagon-unknown-linux-gnu ..
