fdd778278f gcc often inserts it's own names for sections (e.g. 
gnu.linkonce.t.FunctionName). Convert them to "normal" LLVM names,
otherwise linker won't be able to merge them.

cdaf88ff9d 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.

6cec5bdd1c 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
dead in 2.0 and llvm-gcc4 doesn't have that problem nor need the hack.

df277336b8 - FCOPYSIGN custom lowering bug. Clear the sign bit of operand 0 first before 
or'ing in the sign bit of operand 1.
- Tweaking: rather than left shift the sign bit, fp_extend operand 1 first
  before taking its sign bit if its type is smaller than that of operand 0.

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.
