e91ff1d135 MIPS DSP: ADDUH.QB instruction sub-class. 
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164840 91177308-0d34-0410-b5e6-96231b3b80d8

c94a38ff17 1. Add load/store words from the stack 
2. As part of this, added assembly format FEXT_RI16_SP_explicit_ins and
moved other lines for FEXT_RI16 formats to be in the right place in the code.
3. Added mayLoad and mayStore assignements for the load/store instructions added and for ones already there that did not have this assignment.
4. Another patch will deal with the problem of load/store byte/halfword to the stack. This is a particular Mips16 problem.

store this and use it to not emit long nops when the CPU is geode which
doesnt support them.

5a7dd43f04 Remove aligned/unaligned load/store fragments defined in MipsInstrInfo.td and 
use load/store fragments defined in TargetSelectionDAG.td in place of them.
Unaligned loads/stores are either expanded or lowered to target-specific nodes,
so instruction selection should see only aligned load/store nodes.

No changes in functionality.

- BlockAddress has no support of BA + offset form and there is no way to

- All targets are modified to use new interface and X86 backend is enhanced to
  support BA + offset addressing.

04376ebe9f The Mips standalone assembler aliased instruction support. 
The assembler can alias one instruction into another based
on the operands. For example the jump instruction "J" takes
and immediate operand, but if the operand is a register the
assembler will change it into a jump register "JR" instruction.

These changes are in the instruction td file.
