de5a0b65c2 Modify MipsFrameLowering::emitPrologue and emitEpilogue. 
- Use MipsAnalyzeImmediate to expand immediates that do not fit in 16-bit.
- Change the types of variables so that they are sufficiently large to handle
  64-bit pointers.
- Emit instructions to set register $28 in a function prologue after
  instructions which store callee-saved registers have been emitted.

This is similar to implicit register operands.  MC doesn't understand
register liveness and call clobbers.

31867660cb Add a CoveredBySubRegs property to Register descriptions. 
When set, this bit indicates that a register is completely defined by
the value of its sub-registers.

Use the CoveredBySubRegs property to infer which super-registers are
call-preserved given a list of callee-saved registers.  For example, the
ARM registers D8-D15 are callee-saved.  This now automatically implies
that Q4-Q7 are call-preserved.

Conversely, Win64 callees save XMM6-XMM15, but the corresponding
YMM6-YMM15 registers are not call-preserved because they are not fully
defined by their sub-registers.

2dd674fdce Removing unused default switch cases in switches over enums that already account for all enumeration values explicitly. 
(This time I believe I've checked all the -Wreturn-type warnings from GCC & added the couple of llvm_unreachables necessary to silence them. If I've missed any, I'll happily fix them as soon as I know about them)
