The first PR for riscv64 support, implementing it in the front end. Should leave the 32bit instruction set completely intact.

Changes:

Be generic over ELF header bitness
Few new relocations
Instruction decoding for RV64IMCA
Added many new D and W instructions that need to be implemented in the next PR
