056c51e598 Fix bugs in lowering of FCOPYSIGN nodes. 
- FCOPYSIGN nodes that have operands of different types were not handled.
- Different code was generated depending on the endianness of the target.

Additionally, code is added that emits INS and EXT instructions, if they are
supported by target (they are R2 instructions).

a551a48402 Initial 64 bit direct object support. 
This patch allows llvm to recognize that a 64 bit object file is being produced
and that the subsequently generated ELF header has the correct information.

The test case checks for both big and little endian flavors.

Patch by Jack Carter.

imposes a constraint that GOT16 referring to a local symbol or HI16 has to be
followed immediately by a matching LO16 relocation.

f93b863066 Emit all directives except for ".cprestore" during asm printing rather than emit 
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.

b4549e1c0e Pass the llvm IR pointer value and offset to the constructor of 
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.
