8 bit constants can be used.

getExpandedRegion() enables us to create non canonical regions. Those regions
can be used to define the largerst region, that fullfills a certain property.

52061f83e7 Refactor some of the encoding logic into a base class. This keeps us from having 
to add 10+ lines to every instruction.

It may turn out that we can move this base class into it's parent class.

5013f7469e Allow targets to optionally specify custom binary encoder functions for 
operand values. This is useful for operands which require additional trickery
to encode into the instruction. For example, the ARM shifted immediate and
shifted register operands.

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.
