up being a trivial change to create a temporary alloca when the source

 2) load load address with register offset value

Rework the (de-)serialization of macros, as stored in

give each macro definition a proper ID with all of the standard

in a subsequent AST file (e.g., #undef'ing a macro loaded from another
module or from a precompiled header), provide a macro update record
rather than rewriting the entire macro definition. This gives us
greater consistency with the way we handle declarations, and ties
together macro definitions much more cleanly.
