Roger Ferrer Ibanez e41a74e8d2 [RISCV] Pass -target-abi to -cc1as 
The RISC-V assembler needs the target ABI because it defines a flag of the ELF
file, as described in [1].

Make clang (the driver) to pass the target ABI to -cc1as in exactly the same
way it does for -cc1.

Currently -cc1as knows about -target-abi but is not handling it. Handle it and
pass it to the MC layer via MCTargetOptions.

Alex Bradbury 71f45455e1 [RISCV] Add the RISCV target and compiler driver 
As RV64 codegen has not yet been upstreamed into LLVM, we focus on RV32 driver 
support (RV64 to follow).
