- 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.

expand offsets that do not fit in the 16-bit immediate field of load and store
instructions. Also change the types of variables so that they are sufficiently
large to handle 64-bit pointers.

inttypes.h is not supplied in msvc.

Add a test case to show fewer instructions are needed to load an immediate
with the new way of loading immediates.

Widen the instruction encoder that TblGen emits to a 64 bits, which should accomodate every target I can think of offhand.

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

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.

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)

- JALR64 is not needed since N64 does not emit jal. 
- Add template parameter to BranchLink that sets the rt field. 
- Fix the set of temporary registers for O32 and N64.

Implement encoder methods getJumpTargetOpValue and getBranchTargetOpValue
for jmptarget and brtarget Mips tablegen operand types in the code emitter
for old-style JIT. Rename the pc relative relocation for branches - new
name is Mips::reloc_mips_pc16.

DSHD (Double Swap Halfwords within Doublewords). Add a pattern which replaces

WSBW is removed since it is not an instruction the current architectures
support.
