For PR411:
Take an incremental step towards type plane elimination. This change
separates types from values in the symbol tables by finally making use
of the TypeSymbolTable class. This yields more natural interfaces for
dealing with types and unclutters the SymbolTable class.

Solve several related problems by making variable names more unique and

main issue reported in the PR, but its a step in that direction.

For PR1080:
Emit the correct syntax for icmp and fcmp constant expressions. The
predicate goes outside the parentheses not inside. This was a change made
in the assembler without the corresponding change made in llvm-upgrade.

- Remove isSetCCExpensive() etc. These are no longer used.
- Add isSelectExpensive() etc. It's used to tell codegen that select is expensive for a given target, avoid using it if possible. Currently it's only

For PR1077:
Disallow merging of dupliate global variables. It is now illegal to declare
or define two global variables of the same name and same type. llvm-gcc3 is

- Tweaking: rather than left shift the sign bit, fp_extend operand 1 first

globalredefinition3.ll tests that llvm-as will generate an error on
duplicate global variables. This last test is currently XFAIL because
the restriction is not implemented yet.

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.

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.
