Alex Bradbury 13ce95b77f [RISCV] Bugfix createRISCVELFObjectWriter 
r315275 set the IsLittleEndian parameter incorrectly. This patch corrects 
this, and adds a test to ensure such mistakes will be caught in the future.

Alex Bradbury 8cc99f1887 [RISCV] Fix build after r315254

rather than a MCELFObjectTargetWriter*.

Alex Bradbury 9d3f12501a [RISCV] Add common fixups and relocations 
%lo(), %hi(), and %pcrel_hi() are supported and test cases have been added to 
ensure the appropriate fixups and relocations are generated. I've added an 
instruction format field which is used in RISCVMCCodeEmitter to, for 
instance, tell whether it should emit a lo12_i fixup or a lo12_s fixup 
(RISC-V has two 12-bit immediate encodings depending on the instruction 
type).

Alex Bradbury 6b2cca7f8f [RISCV] Add bare-bones RISC-V MCTargetDesc 
This is enough to compile and link but doesn't yet do anything particularly 
useful. Once an ASM parser and printer are added in the next two patches, the 
whole thing can be usefully tested.
