Adds RISCV support to Keystone

null-cell commented 1 year ago

adds the support for RISC-V architecture (refers to #491) from LLVM 9.0.1 version - the first official release of RISC-V to LLVM,
generic-rv64 (RV64GC) and generic-rv32 (RV64GC) are available, but this should be easily extended to more specific requirements,
for Ks init, KS_ARCH_RISCV arch is implemented and KS_MODE_RISCV64, KS_MODE_RISCV32, KS_MODE_LITTLE_ENDIAN modes are available,
implements FeatureBitset instead of uint_8/uint_64 for calculating features like all new LLVM development,

This pull request can also be a reference point to whoever wants to port other architectures from newer LLVM versions.

Very high quality integration! And I can't find further obvious errors. LGTM overall.
