reimplement support for GS and FS relative address space matching
by having X86DAGToDAGISel::SelectAddr get passed in the parent node
of the operand match (the load/store/atomic op) and having it get
the address space from that, instead of having special FS/GS addr
mode operations that require duplicating the entire instruction set
to support.
This makes FS and GS relative accesses *far* more predictable and
work much better. It also simplifies the X86 backend a bit, more
to come.
There is still a pending issue with nodes like ISD::PREFETCH and
X86ISD::FLD, which really should be MemSDNode's but aren't.

CombinerAA cannot assume that different FrameIndex's never alias, but can instead use
MachineFrameInfo to get the actual offsets of these slots and check for actual aliasing.

Simplify ARM callee-saved register handling by removing the distinction
between the high and low registers for prologue/epilogue code. This was
a Darwin-only thing that wasn't providing a realistic benefit anymore.
Combining the save areas simplifies the compiler code and results in better
ARM/Thumb2 codegen.
For example, previously we would generate code like:
push {r4, r5, r6, r7, lr}
add r7, sp, #12
stmdb sp!, {r8, r10, r11}
With this change, we combine the register saves and generate:

To invoke the new construction mechanism just pass '-regalloc=pbqp -pbqp-builder' to llc. To provide custom constraints a
