2ab36d3502 Begin adding static dependence information to passes, which will allow us to 
perform initialization without static constructors AND without explicit initialization
by the client.  For the moment, passes are required to initialize both their
(potential) dependencies and any passes they preserve.  I hope to be able to relax
the latter requirement in the future.

d0eeeeb558 Remove the x86 MOV{32,64}{rr,rm,mr}_TC instructions. 
The reg-reg copies were no longer being generated since copyPhysReg copies
physical registers only.

The loads and stores are not necessary - The TC constraint is imposed by the
TAILJMP and TCRETURN instructions, there should be no need for constrained loads
and stores.

77f42b5278 PR8359: The ARM backend may end up allocating registers D16 to D31 when 
"-mattr=+vfp3" is specified. However, this will not work for hardware that
only supports 16 registers.  Add a new flag to support -"mattr=+vfp3,+d16".

40ef4fe82a Properly handle reloading and spilling around partial redefines in 
LocalRewriter.

This is a bit of a hack that adds an implicit use operand to model the
read-modify-write nature of a partial redef. Uses and defs are rewritten in
separate passes, and a single operand would never be processed twice.
