e1e9aa99ae Major update of llvm-upgrade: 
1. Completely revise the type system so that types are handled as const
   objects and not created multiple times, cloned, or otherwise copied.
   This gets around memory issues, saves memory, and also emulates LLVM's
   no-two-types-of-the-same-shape-created semantics.
2. Adjust the handling of global names. Basically, we cannot rename them
   for a variety of reasons: linking, forward references, etc.
3. Detect global names that have name conflicts as the result of collapsed
   type planes or redefinitions that llvm-as no longer accepts. These will
   produce warnings on stderr and one of the globals will be renamed.
4. Rename ParserInternals.h as UpgradeInternals.h so it doesn't conflict
   in the debugger with ParserInternals.h from lib/AsmParser.
5. Move the guts of the TypeInfo class into the grammar so we aren't
   implementing large functions in a header file. This also helps with
   debugging a bit.

4f14887126 Change the syntax for parameter attributes: 
1. The @ sign is no longer necessary.
2. We now support "function attributes" as parameter attribute 0.
3. Instead of locating the return type attributes after the type of a
   function result, they are now located after the function header's
   closing paranthesis and before any alignment or section options.
4. The way has been prepared for a new "noreturn" function attribute but
   there is no support for recognizing it in the lexer nor doing anything
   with it if it does get set.
5. The FunctionType::getParamAttrsText method now has support for
   returning multiple attributes. This required a change in its interface.

I'm unhappy that this change leads to 6 new shift/reduce conflicts, but
in each case bison's decision to choose the shift is correct so there
shouldn't be any damage from these conflicts.
