Demonstrate how to generate vadd/vfadd intrinsic functions (explicitly api) and tests. 1. add -gen-riscv-vector-builtins for clang builtins. 2. add -gen-riscv-vector-builtin-codegen for clang codegen. 3. add -gen-riscv-vector-header for riscv_vector.h. It also generates ifdef directives with extension checking, base on D94403 <https://reviews.llvm.org/D94403>. 4. add -gen-riscv-vector-generic-header for riscv_vector_generic.h. Generate overloading version Header for generic api. https://github.com/riscv/rvv-intrinsic-doc/blob/master/rvv-intrinsic-rfc.md#c11-generic-interface 5. add -gen-riscv-vector-test and -gen-riscv-vector-generic-test for clang tests. I think using the same td file to generate tests can avoid duplicate works but there is no test generator are writen in tablengen backend now. (ArmNeonTest was deprecated). In order to generate separated test files, I need modify clang_generate_header function of CMake to support passing more arguments. 6. add gen-riscv-v-tests.sh which generates all clang tests and use 'update_cc_test_checks.py' to update expected result. 7. update tblgen doc for riscv related options. riscv_vector.td also defines some unused type transformers for vadd, because I think it could demonstrate how tranfer type work and we need them for whole intrinsic functions implementation in the future.
