Add misaligned memory access for spike.
The spec does not forbid the misaligned memory access. And the gcc
will generate vector load/store to access misaligned memory by
default.
Currently the QEMU supports this feature, so to support in spike
is also make sense.
Reference test case: gcc/gcc/testsuite/gcc.dg/vect/vect-align-1.c
