Remove old backwards compatibility support from the parser for autoupgrading

the old malloc/free instructions, and for 'sext' and 'zext' as function 
attributes (they are spelled signext/zeroext now), and support for result
value attributes being specified after a function.

Additionally, diagnose invalid attributes on functions with an error message
instead of an abort in the verifier.
