D93611 <https://reviews.llvm.org/D93611>, D93612 <https://reviews.llvm.org/D93612>, D93613 <https://reviews.llvm.org/D93613>, and D93614 <https://reviews.llvm.org/D93614> have been reviewed and accepted. I change the version number of vector extension to v1.020201218, i.e., append the date of commit 08a0b464 in riscv-v-spec to v1.0.

Currently, there is no v1.0 tag in riscv-v-spec. That is why I use the date of the commit as the draft version number. We hope v1.0 could be merged into LLVM 12. I am not sure whether it is an acceptable way to do it or not.
