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.

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.

603f69dc2c Define ADJCALLSTACKDOWN/UP nodes. These nodes are emitted regardless of whether 
or not it is in mips16 mode. Define MipsPseudo (mode-independant pseudo) and
PseudoSE (mips32/64 pseudo) classes.

68c10a2ff7 Remove variable_ops from call instructions in most targets. 
Call instructions are no longer required to be variadic, and
variable_ops should only be used for instructions that encode a variable
number of arguments, like the ARM stm/ldm instructions.
