analyzer: return a concrete offset for cast_regions
This patch fixes a bug where maybe_fold_sub_svalue did not fold the
access of a single char from a string to a char when the offset was zero
because get_relative_concrete_offset did return false for cast_regions.
Regrtested on Linux x86_64.

New overloaded method.
