Similar to the existing implementations for X86 and PPC, support
symbolizing branch targets for AArch64. Do not omit the address for ADRP
as the target is typically not at an intended location.

Deleting a basic block removes all references from jump tables, which
is O(n). When freeing a MachineFunction, all basic blocks are deleted
before the jump tables, causing O(n^2) runtime. Fix this by deallocatin

Reused an existing test case, this also shows the difference in the resulting
block order. If preferred, I can also write a separate test case.

MachineBlockPlacement has quadratic runtime in the number of
predecessors: in some situation, for an edge, all predecessors of the
successor are considered.
Limit the number of considered predecessors to bound

Replace the DenseMap from blocks to their innermost loop a vector
indexed by block numbers, when possible.
This requires updating the loop info when blocks are renumbered. This
