[MemorySSA] Don't bail on phi starting access
When calling getClobberingMemoryAccess() with MemoryLocation on a
MemoryPHI starting access, the walker currently immediately bails
and returns the starting access. This makes sense for the API that
does not accept a location (as we wouldn't know what clobber we
should be checking for), but doesn't make sense for the
MemoryLocation-based API. This means that it can't look through
a MemoryPHI if it's the starting access, but can if there is one
more non-clobbering def in between. This patch removes the limitation.
