  target/riscv: configure and turn on vector extension from command line 
(2020-06-26 14:22:15 -0700)

----------------------------------------------------------------
This PR contains two patches to improve PLIC support in QEMU.

The rest of the PR is adding support for the v0.7.1 RISC-V vector
extensions. This is experimental support as the vector extensions are
still in a draft state.
