[mips] Add support for .cpload. Summary: This directive is used for setting up $gp in the beginning of a function. It expands to three instructions if PIC is enabled: lui $gp, %hi(_gp_disp) addui $gp, $gp, %lo(_gp_disp) addu $gp, $gp, $reg _gp_disp is a special symbol that the linker sets to the distance between the lui instruction and the context pointer (_gp).

[llvm-objdump] Support detection of feature bits from the object and implement this for Mips. Summary: The Mips implementation only covers the feature bits described by the ELF e_flags so far. Mips stores additional feature bits such as MSA in the .MIPS.abiflags section. Also fixed a small bug this revealed where microMIPS wouldn't add the EF_MIPS_MICROMIPS flag when using -filetype=obj.

Move the Mips target to storing the ABI in the TargetMachine rather than on MipsSubtargetInfo. This required a bit of massaging in the MC level to handle this since MC is a) largely a collection of disparate classes with no hierarchy, and b) there's no overarching equivalent to the TargetMachine, instead only the subtarget via MCSubtargetInfo (which is the base class of TargetSubtargetInfo). We're now storing the ABI in both the TargetMachine level and in the MC level because the AsmParser and the TargetStreamer both need to know what ABI we have to parse assembly and emit objects. The target streamer has a pointer to the one in the asm parser and is updated when the asm parser is created. This is fragile as the FIXME comment notes, but shouldn't be a problem in practice since we always create an asm parser before attempting to emit object code via the assembler. The TargetMachine now contains the ABI so that the DataLayout can be constructed dependent upon ABI. All testcases have been updated to use the -target-abi command line flag so that we can set the ABI without using a subtarget feature. Should be no change visible externally here. llvm-svn: 227102

[mips] Improve error/warning messages and testing for the .cpload assembler directive. Summary: Improved warning message when using .cpload inside a reorder section and added an error message for using .cpload with Mips16 enabled. Modified the tests to fit with the changes mentioned above, added a test-case for the N32 ABI in cpload.s and did some reformatting to make the tests easier to read.
