This is the first part of v6 patchset. The changelog of v6 is only coverd
the part1.
Features:
* support specification riscv-v-spec-0.7.1.
* support basic vector extension.
* support Zvlsseg.
* support Zvamo.
* not support Zvediv as it is changing.
* SLEN always equals VLEN.
* element width support 8bit, 16bit, 32bit, 64bit.
Changelog:
v6
* keep vector CSR in read/write order
* define fields name of VTYPE just like specification.
v5
* vector registers as direct fields in RISCVCPUState.
* mov the properties to last patch.
* check RVV in vs().
* check if rs1 is x0 in vsetvl/vsetvli.
* check VILL, EDIV, RESERVED fileds in vsetvl.
v4
* adjust max vlen to 512 bits.
* check maximum on elen(64bits).
* check minimum on vlen(128bits).
* check if rs1 is x0 in vsetvl/vsetvli.
* use gen_goto_tb in vsetvli instead of exit_tb.
* fixup fetch vlmax from rs2, not env->vext.type.
v3
* support VLEN configure from qemu command line.
* support ELEN configure from qemu command line.
* support vector specification version configure from qemu command line.
* only default on for "any" cpu, others turn on from command line.
* use a continous memory block for vector register description.
V2
* use float16_compare{_quiet}
* only use GETPC() in outer most helper
* add ctx.ext_v Property
