4a8c999803 Added a separate class (PBQPBuilder) for PBQP Problem construction. This class can be extended to support custom constraints.
For now the allocator still uses the old (internal) construction mechanism by default. This will be phased out soon assuming 
no issues with the builder system come up.

To invoke the new construction mechanism just pass '-regalloc=pbqp -pbqp-builder' to llc. To provide custom constraints a
Target just needs to extend PBQPBuilder and pass an instance of their derived builder to the RegAllocPBQP constructor.

015641f659 Invert the logic of reachesChainWithoutSideEffects(). What we want to check is that there is
NO path to the destination containing side effects, not that SOME path contains no side effects.
In  practice, this only manifests with CombinerAA enabled, because otherwise the chain has little
to no branching, so "any" is effectively equivalent to "all".

670e1915c0 Add target-specific DAG combiner for BUILD_VECTOR and VMOVRRD. An i64
value should be in GPRs when it's going to be used as a scalar, and we use
VMOVRRD to make that happen, but if the value is converted back to a vector
we need to fold to a simple bit_convert.  Radar 8407927.

8c2bde65f0 Teach machine sink to
1) Do forward copy propagation. This makes it easier to estimate the cost of the
   instruction being sunk.
2) Break critical edges on demand, including cases where the value is used by
   PHI nodes.
Critical edge splitting is not yet enabled by default.

a43c86b354 MC/AsmParser: Add support for 'a + 4@GOTPCREL' and friends, by reconsing the

 - Gross, but this a corner case we don't expect to see often in practice, but
   it is worth accepting.
 - Also improves diagnostics on invalid modifiers.
