[LAA] Replace symbolic strides for translated pointers earlier (NFC).

Move up replaceSymbolicStrideSCEV before isNoWrap. It needs to be called
after hasComputableBounds, as this may create an AddRec via PSE, which
replaceSymbolicStrideSCEV will look up.

This is in preparation for simplifying isNoWrap.
