914b2a7e37 New store optimization. 
New functions RegValIsKnown and RegValIsUnknown should be used instead of
direct compares against zero, so we can change the "unknown" representation
one day.

b4326d1930 Place all declarations that are local to a function into the local function 
scope. Apart from some other advantages, this works around a bug where having
an external identifier in global scope and using an "extern" declaration for
exactly the same identifier in a function did not work, because the assembler
refused to export and import one and the same identifier. Since the import
now imports into local scope, both identifiers are distinct for the assembler
and the (valid) C code works.

9464c7dd29 Change the .LOCAL command so that the cheap local symbol prefix is kept. 
This allows to create macros with local labels that expand to cheap local
symbols when the macro is expanded.
