For PR950:
Remove all grammar conflicts from assembly parsing. This change involves:
1. Making the "type" keyword not a primitive type (removes several
reduce/reduce conflicts)
2. Being more specific about which linkage types are allowed for functions
and global variables. In particular "appending" can no longer be
specified for a function. A differentiation was made between the various
internal and external linkage types.
3. Introduced the "define" keyword which is now required when defining a
function. This disambiguates several cases where a named function return
type could get confused with the definition of a new type. Using the
keyword eliminates all shift/reduce conflicts and the remaining
reduce/reduce conflicts.
These changes are necessary to implement the function parameter attributes
that will be introduced soon. Adding the function parameter attributes in
the presence of the shift/reduce and reduce/reduce conflicts led to severe
ambiguities that caused the parser to report syntax errors that needed to
be resolved. This patch resolves them.
