f4cd5a4801 Add XMM1 as a second return value register for f32 and f64 on x86-64. This 
is needed for the x86-64-ABI handling of structs that contain floating-point
members that are returned by value.

41d0309ce8 Fix a bug where an incorrect bit mask would be generated if a target's last asm 
string began at a power of 2 in the string index.  For example, if "ret" started
at position 16, the ret instruction would be assigned code 16, but the mask would be AsmChars[] + Code & 15, not Code & 31.

4ad5a5201c Add operator= implementations to SparseBitVector, allowing it to be used in GVN. This results 
in both time and memory savings for GVN.  For example, one testcase went from 10.5s to 6s with
this patch.

98ed2df5f3 The "stacksave is not nounwind problem" no longer 
needs to be fixed here - a previous commit made sure
that intrinsics always get the right attributes.
So remove no-longer needed code, and while there use
Intrinsic::getDeclaration rather than getOrInsertFunction.

be i8*, was an array*).

5c2c09c01b Mark calls to llvm.stacksave, llvm.stackrestore as 
nounwind.  When such calls are inlined into something
else that is invoked, they were getting changed to invokes,
which is badness.
