*	[RISCV] Add codegen support for ilp32f, ilp32d, lp64f, and lp64d ("hard ↵	Alex Bradbury	2019-03-30	1	-12/+12
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	float") ABIs This patch adds support for the RISC-V hard float ABIs, building on top of rL355771, which added basic target-abi parsing and MC layer support. It also builds on some re-organisations and expansion of the upstream ABI and calling convention tests which were recently committed directly upstream. A number of aspects of the RISC-V float hard float ABIs require frontend support (e.g. flattening of structs and passing int+fp for fp+fp structs in a pair of registers), and will be addressed in a Clang patch. As can be seen from the tests, it would be worthwhile extending RISCVMergeBaseOffsets to handle constant pool as well as global accesses.

*	[RISCV] Support -target-abi at the MC layer and for codegen	Alex Bradbury	2019-03-09	1	-0/+40
	This patch adds proper handling of -target-abi, as accepted by llvm-mc and llc. Lowering (codegen) for the hard-float ABIs will follow in a subsequent patch. However, this patch does add MC layer support for the hard float and RVE ABIs (emission of the appropriate ELF flags https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md#-file-header). ABI parsing must be shared between codegen and the MC layer, so we add computeTargetABI to RISCVUtils. A warning will be printed if an invalid or unrecognized ABI is given.
