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.

This method emits nodes for passing byval arguments in registers and stack.
This has the same functionality as existing functions PassByValArg64 and
WriteByValArg which will be deleted later.

This method copies byval arguments passed in registers onto the stack and has
the same functionality as existing functions CopyMips64ByValRegs and
ReadByValArg which will be deleted later.

Currently, it is enabled only if option "enable-mips-tail-calls" is given and
all of the callee's arguments are passed in registers.

1. Remove RA from list of allocatable registers
2. Enable d,y,r constraint inline assembly instructions

- BlockAddress has no support of BA + offset form and there is no way to
propagate that offset into machine operand;
- Add BA + offset support and a new interface 'getTargetBlockAddress' to
simplify target block address forming;
- All targets are modified to use new interface and X86 backend is enhanced to
support BA + offset addressing.

to prevent it from being clobbered. mips uses $gp to access small data section.

The frame object which points to the dynamically allocated area will not be
needed after changes are made to cease reserving call frames.

single-precision load and store.
Also avoid selecting LUXC1 and SUXC1 instructions during isel. It is incorrect
to map unaligned floating point load/store nodes to these instructions.
