73ee5ff6b8 (1) Added special register class containing (for now) %fsr. 
Fixed spilling of %fcc[0-3] which are part of %fsr.

(2) Moved some machine-independent reg-class code to class TargetRegInfo
    from SparcReg{Class,}Info.

151f7484ab NOP instructions are pseudo-instructions. We should not have them explicitly in 
our representation, since they are usually special cases of already-existing
instructions.

This abstracts away methods that let a pass create and verify a NOP instruction,
without relying on a `NOP' enum to be in existence in the target's instruction
info descriptor.

b525ce97cc * Keep track of register alignment as well as register size 
* Add comments
* Add a new allocation_order iterator for register classes which targets may
  use to control the register order and available registers based on properties
  of the function being compiled.
* Remove access to FP and SP registers
* Add new callframe setup opcode support
* Eliminate moveImm2Reg method
* Revamp frame offset handling and prolog/epilog code generation
