Bill Wendling 2b8fc31df9 The personality function on Darwin needs a global stub. We then refer to 
that global stub instead of doing the ".set" thingy we were doing before.

Steve Naroff 4292bde14f Fix the following bug submitted by Justin Handville. 
int main(int argc, char* argv[])
{
  return 0;
}

After speaking briefly with Chris, we decided this should be a front-end fix.

The fix...have Sema::GetTypeForDeclarator() do the default function/array conversion, as
I outlined in the 9/9 email on this topic.

Since this conversion is done before Sema::ParseParamDeclarator(), I thought I could
remove the conversion from Sema::ParseParamDeclarator(). Unfortunately, this didn't work.
The conversion apparently needs to be done in both places (which doesn't make sense to me).

Will investigate.

Chris Lattner 58c227bd09 Emit: 
cmpl    %eax, %ecx
        setae   %al
        movzbl  %al, %eax

instead of:

        cmpl    %eax, %ecx
        setb    %al
        xorb    $1, %al
        movzbl  %al, %eax

when using logical not of a C comparison.

Chris Lattner 33a7f51412 1. Don't call Value::getName(), which is slow. 
2. Lower calls to fabs and friends to FABS nodes etc unless the function has
   internal linkage.  Before we wouldn't lower if it had a definition, which
   is incorrect.  This allows us to compile:

define double @fabs(double %f) {
        %tmp2 = tail call double @fabs( double %f )
        ret double %tmp2
}

into:

_fabs:
        fabs f1, f1
        blr

Evan Cheng 637395e6bd It's not safe to rematerialize MOV32r0 etc. by simply cloning the original 
instruction. These are implemented with xor which will modify the conditional
code. They should be rematerialized as move instructions.

Ted Kremenek bd9cc5ca89 Fixed LiveVariables to no longer track the liveness of function pointers 
that refer to direct function calls.
