Convert all tabs to spaces in assembly sources, unify indentation Previously the assembly sources had mixed indentation consisting of both spaces and tabs, making it quite hard to read unless the right tab size was used in the editor. Tabs have been interpreted as 4 spaces in most cases, matching the surrounding code.

Tabs have been interpreted as 4 spaces in most cases, matching the surrounding code.
