Construct LLVM Support module about CSKY target parser and attribute parser. It refers implementation of GNU binutils and GCC.

Now we only support CSKY 800 series cpus and newer cpus in the future undering CSKYv2 ABI specification. There are 11 archs including ck801, ck802, ck803, ck803s, ck804, ck805, ck807, ck810, ck810v, ck860, ck860v.

Every arch has base extensions, the cpus of that arch family have more extended extensions than base extensions. We need specify extended extensions for every cpu. Every extension has its enum value, name and related llvm feature string with +/-. Every enum value represents a bit of uint64_t integer.
