Pengcheng Wang 7a5b040e20 [RISCV] Add initial support of memcmp expansion 
There are two passes that have dependency on the implementation
of `TargetTransformInfo::enableMemCmpExpansion` : `MergeICmps` and
`ExpandMemCmp`.

This PR adds the initial implementation of `enableMemCmpExpansion`
so that we can have some basic benefits from these two passes.

We don't enable expansion when there is no unaligned access support
currently because there are some issues about unaligned loads and
stores in `ExpandMemcmp` pass. We should fix these issues and enable
the expansion later.

Vector case hasn't been tested as we don't generate inlined vector
instructions for memcmp currently.
