Make MCInstrInfo available to the MCInstPrinter. This will be used to remove getInstructionName and the static data it contains since the same tables are already in MCInstrInfo.

them as machine instructions. Directives ".set noat" and ".set at" are now
emitted only at the beginning and end of a function except in the case where
they are emitted to enclose .cpload with an immediate operand that doesn't fit
in 16-bit field or unaligned load/stores.

Also, make the following changes:
- Remove function isUnalignedLoadStore and use a switch-case statement to
  determine whether an instruction is an unaligned load or store.

- Define helper function CreateMCInst which generates an instance of an MCInst
  from an opcode and a list of operands.

If EmitNOAT is true, directives ".set noat" and ".set at" are emitted at the
beginning and end of a function.

MachinePointerInfo when getStore is called to create a node that stores an
argument passed in register to the stack. Without this change, the post RA 
scheduler will fail to discover the dependencies between the stores
instructions and the instructions that load from a structure passed by value.

These changes allow us to compile big endian from the command line for 32 bit
Mips targets. This patch will result in code and data actually being produced
in the correct endianess.

For example, this pattern 
(select (setcc lhs, rhs, cc), true, 0)
is transformed to this one:
(select (setcc lhs, rhs, inverse(cc)), 0, true)

This enables MipsDAGToDAGISel::ReplaceUsesWithZeroReg (added in r152280) to
replace 0 with $zero.

For example, the first instruction in the code below can be eliminated if the
use of $vr0 is replaced with $zero: 

addiu $vr0, $zero, 0
add $vr2, $vr1, $vr0

add $vr2, $vr1, $zero

- Only aligned load and store nodes should be matched to select reg+imm

- MIPS does not have support for f64 unaligned load or store instructions.
