eefee972cf Turn some fp stackifier assertion into errors to avoid silently generating bad code when assertions are off. rdar://8540457.

de78ccb013 Move the ARM so_imm encoding into a custom operand encoder and remove the 
explicit handling of the instructions referencing it from the MC code
emitter.

d1f06024ce 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.

f4cf5bef46 Add custom encoder for the 's' bit denoting whether an ARM arithmetic 
instruction should set the processor status flags or not. Remove the now
unnecessary special handling for the bit from the MCCodeEmitter.

394bc160f9 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.

79d57782ad Split out the "size" field from the encoding. The newer documentation has it as 
a separate bit in the coding.

63f757463c 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.

499fe39d23 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.

bbb91c6a1c 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".
