Matt Arsenault cc5a1b3dd9 llvm-reduce: Add cloning of target MachineFunctionInfo
MIR support is totally unusable for AMDGPU without this, since the set
of reserved registers is set from fields here.

Add a clone method to MachineFunctionInfo. This is a subtle variant of
the copy constructor that is required if there are any MIR constructs
that use pointers. Specifically, at minimum fields that reference
MachineBasicBlocks or the MachineFunction need to be adjusted to the
values in the new function.
