a7f4ca5fd0 Place bit_cast<>() in the v8::base:: namespace.
This prevents ambiguity errors in C++20 due to ADL when casting types in
std::, which gains std::bit_cast<>().

fcd3ef4821 [riscv64][wasm]Add Vector instrs
- Add vsetivli/I8x16Add/vl/vse8
 - In Rvv, Vector regs is different from Float Regs. But in this cl, in order to facilitate modification, it is assumed that the vector register and float register share a set of register codes.
 - Because v0 is mask reg, we can't allocate it . And transfer float into vector reg, so i delete ft0 from AllocateReg.
