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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32770 91177308-0d34-0410-b5e6-96231b3b80d8
