7da3bde866 Fix a typo introduced by the cast patch that horribly broke a lot of vector 
code.  Testcase here: Transforms/ConstProp/2006-11-30-vector-cast.ll

b8611ec8bc Don't fold "ptrtoint GV to bool" since this should be doing a truncate not 
a comparison against zero. Instead fold setne(GV,null) and seteq(GV,null)
to ConstantBool::True or ConstantBool::False, respectively.

0085a28d13 - Use a different wrapper node for RIP-relative GV, etc. 
- Proper support for both small static and PIC modes under X86-64
- Some (non-optimal) support for medium modes.

46b96055cf implement cast.ll:test35. With this, we recognize: 
unsigned short swp(unsigned short a) {
       return ((a & 0xff00) >> 8 | (a & 0x00ff) << 8);
}

as an idiom for bswap.

5d52135a14 Upgrade the ugly darwin 64-bit bswap idiom (bswap %eax / bswap %edx / 
xchgl %eax, %edx) to llvm.bswap.i64.  This compiles:

long long test2(long long A) {
  return _OSSwapInt64(A);
}

to:

_test2:
        movl 8(%esp), %eax
        movl 4(%esp), %edx
        bswapl %eax
        bswapl %edx
        ret

instead of:

_test2:
        movl 8(%esp), %edx
        movl 4(%esp), %eax
        bswap   %eax
        bswap   %edx
        xchgl   %eax, %edx
        ret

GCC manages (with -fomit-frame-pointer) the uglier:

_test2:
        subl    $4, %esp
        movl    8(%esp), %eax
        movl    12(%esp), %edx
        bswap   %eax
        bswap   %edx
        xchgl   %eax, %edx
        addl    $4, %esp
        ret
