[PBQP] Tidy up CostAllocator.h: fix variable case, rename CostPool to ValuePool.

No functional change. This just brings things more in-line with coding
standards, and makes ValuePool's functionality clearer (it's not tied to pooling
costs, and we may want to use it to hold other things in the future).

[PBQP] Re-commit r220642 with a workaround for quirky Visual Studio behavior.

Apparently unique_ptr'ifying NodeMetadata exposed an issue in VS where it
occasionally tries to synthesize copy constructors instead of moves. Hopefully
explicitly deleting the copy constructor and defining the move constructor will
fix this.

Add an option to the LTO code generator to disable vectorization during LTO

We used to always vectorize (slp and loop vectorize) in the LTO pass pipeline.

r220345 changed it so that we used the PassManager's fields 'LoopVectorize' and
'SLPVectorize' out of the desire to be able to disable vectorization using the
cl::opt flags 'vectorize-loops'/'slp-vectorize' which the before mentioned
fields default to.
Unfortunately, this turns off vectorization because those fields
default to false.
This commit adds flags to the LTO library to disable lto vectorization which
reconciles the desire to optionally disable vectorization during LTO and
the desired behavior of defaulting to enabled vectorization.

We really want tools to set PassManager flags directly to enable/disable
vectorization and not go the route via cl::opt flags *in*
PassManagerBuilder.cpp.

[PBQP] Explicitly define copy/move operations for NodeMetadata to keep VS happy.

Hopefully this fixes the bug that was introduced in r220642, and not-quite-fixed
in r220649.

InstCombine: Fix a combine assuming that icmp operands were integers

An icmp may have pointer arguments, it isn't limited to integers or
vectors of integers.

This fixes PR21388.

Include stddef.h before including cxxabi.h

On FreeBSD 10.0, size_t needs to be defined before including cxxabi.h.
Currenty HAVE_CXXABI_H is not defined on FreeBSD because of that reason.
This patch teaches cmake and configure how to include it.

[ARM] Select VMAXNM and VMINNM regardless of operand order

Currently, the ARM backend will select the VMAXNM and VMINNM for these C
expressions:
  (a < b) ? a : b
  (a > b) ? a : b
but not these expressions:
  (a > b) ? b : a
  (a < b) ? b : a

This patch allows all of these expressions to be matched.

Add MapVector::rbegin(), MapVector::rend() to completment MapVector::begin(), MapVector::end().

These just delegate to the underlying vector type in the MapVector.

Also just add in some sanity unittests.
