Reed Kotler 3589dd74ac This patch is for the implementation of mips16 complex pattern addr16.
Previously mips16 was sharing the pattern addr which is used for mips32
and mips64. This had a number of problems:
1) Storing and loading byte and halfword quantities for mips16 has particular
problems due to the primarily non mips16 nature of SP. When we must
load/store byte/halfword stack objects in a function, we must create a mips16
alias register for SP. This functionality is tested in stchar.ll.
2) We need to have an FP register under certain conditions (such as 
dynamically sized alloca). We use mips16 register S0 for this purpose.
In this case, we also use this register when accessing frame objects so this
issue also affects the complex pattern addr16. This functionality is
tested in alloca16.ll.

The Mips16InstrInfo.td has been updated to use addr16 instead of addr.

The complex pattern C++ function for addr has been copied to addr16 and
updated to reflect the above issues.

Reed Kotler 210ebe93f3 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.

Akira Hatanaka 3e7ba76157 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.

Jakob Stoklund Olesen ed6c0408fa 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.
