[RISCV] AsmParser support for the li pseudo instruction The implementation follows the MIPS backend and expands the pseudo instruction directly during asm parsing. As the result, only real MC instructions are emitted to the MCStreamer. The actual expansion to real instructions is similar to the expansion performed by the GNU Assembler. This patch supersedes D41949. Differential Revision: https://reviews.llvm.org/D46118 Patch by Mario Werner. llvm-svn: 334203

[RISCV] Support llvm-objdump -M no-aliases and -M numeric Summary: Now that llvm-objdump allows target-specific options, we match the `no-aliases` and `numeric` options for RISC-V, as supported by GNU objdump. This is done by overriding the variables used for the command-line options, so that the command-line options are still supported. This patch updates all tests using `llvm-objdump -riscv-no-aliases` to use `llvm-objdump -M no-aliases`.
