Sam Elliott d57de491be [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`.

Alex Bradbury 1ffceaa543 [RISCV] Match GNU tools canonical JALR and add aliases
The canonical GNU form of JALR resembles a load/store instruction rather
than placing the immediate offset as a separate argument, so match this
behaviour. Also add parser-only aliases for the three-operand form, and
add other shorter aliases also emitted by GNU tools.
