Fixes #175. The issue seems to be that the mapping symbols are read from the object file itself when it's first read, before objdiff combines any sections, so only the first function has accurate mappings.
To fix this, I added a
post_initstep to the Arch trait that now reads the mapping symbols from the combined text section instead. If other arches have similar issues with combined sections,post_initmight help for those as well.
