Merging r168471:
Mips direct object xgot support
This patch provides support for the MIPS relocations:
*) R_MIPS_GOT_HI16
*) R_MIPS_GOT_LO16
*) R_MIPS_CALL_HI16
*) R_MIPS_CALL_LO16
These are used for large GOT instruction sequences.
Contributer: Jack Carter
Merging r168460:
[mips] Generate big GOT code.
Merging r168458:
[mips] Simplify lowering functions in MipsISelLowering.cpp by using the helper
functions added in r168456.
Merging r168456:
[mips] Add helper functions that create nodes for computing address.
Merging r168455:
[mips] Add command line option "-mxgot".
Merging r168453:
[mips] When a node which loads from a GOT is created, pass a MachinePointerInfo
referring to a GOT entry.
Merging r168450:
[mips] Add target operand flag enums for big GOT relocations.
Merging r168448:
Add relocations used for mips big GOT.
