Add andm, orm, xorm, eqvm, nndm, negm, pcvm, lzvm, and tovm intrinsic
instructions, a few pseudo instructions to expand logical intrinsic
using VM512, a mechnism to expand such pseudo instructions, and
regression tests. Also, assign vector mask types and vector mask
register classes correctly. This is required to use VM512 registers
as function arguments.

SX Aurora VE uses an intermediate representation similar to VP as its MIR.
VE itself uses invidiual VL register as its own vector length register at
the hardware level. So, LLVM needs to insert load VL (LVL) instruction just
before vector instructions if the value of VL is changed. This LVLGen pass
generates LVL instructions for such purpose. Previously, a bug is pointed
out in D91416. This patch correct this bug and add a regression test.

Change the way to truncate i64 to i32 in I64 registers. VE assumed
sext values previously. Change it to zext values this time to make
it match to the LLVM behaviour.

Add lvm/svm intrinsic instructions and a regression test. Change
RegisterInfo to specify that VM0/VMP0 are constant and reserved
registers. This modifies a vst regression test, so update it.
Also add pseudo instructions for VM512 register classes
and mechanism to expand them after register allocation.

The VE backend represents vector instructions with an explicit 'i32'
vector length operand. In the VE ISA, the vector length is always read
from the VL hardware register. The LVLGen pass inserts 'lvl'
instructions as necessary to set VL to the right value before each
vector instruction.
