RegAllocPBQP: Do not assign reserved physical register
(0) RegAllocPBQP: Since getRawAllocationOrder() may return a collection that includes reserved physical registers, iterate to find an un-reserved physical register.
(1) VirtRegMap: Enforce the invariant: "no reserved physical registers" in assignVirt2Phys(). Previously, this was checked only after the fact in VirtRegRewriter::rewrite.
(2) MachineVerifier: updated the test per MatzeB's review.
(3) +testcase
