This implements very basic support for RISC-V mapping symbols in llvm-objdump, sharing the implementation with how Arm/AArch64/CSKY implement this feature. This only supports the `$x` (instruction) and `$d` (data) mapping symbols for RISC-V, and not the version of `$x` which includes an architecture string suffix.

## This CHECKs objdump's handling of wide instruction encodings, and how it
|
|
## groups the instruction bytes when disassembling.

##
|
|
## This is written in YAML because using `.byte` emits the wrong mapping
|
|
## symbols.
