80c6c3bbff this final call to canLosslesslyBitCastTo is dead, because ValueRequiresCast
is only called on integers.

57d8637468 eliminate some uses of canLosslesslyBitCastTo, this actually makes the code stronger, by nuking
relational pointer comparisons with casts.

90e2f63151 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.

73d6cf12ad - 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.

2c261789d3 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.

- New target type "mingw" was introduced
- Same things for both mingw & cygwin are marked as "cygming" (as in

& cygwin

8c57dfb1ae Two changes:
1. Switch expression and cases are compared signed and are sign extended.
2. For function results needing extended, do SIGN_EXTEND if the SExtAttribute
   is set and ZERO_EXTEND if the ZExtAttribute is set, otherwise just let
   the Legalizer do ANY_EXTEND.
This fixes the recent regression in kimwitu++ and probably the llvm-gcc
bootstrap issue we had today.
