CalleeWithThisReturn can be left initialized if HasThisReturn() is false.
This change reverses the order of checks in EmitFunctionEpilog such that
CalleeWithThisReturn is only examined when it has a meaningful value.

and we copied the current value of the variable to the temporary,
make sure that we register an intrinsic use of that value with
the optimizer so that the value won't get released until we have
a chance to retain it.

Summary:
For non-dynamic classes (no virtual bases), member data pointers are
simple offsets from the base of the record.  Dynamic classes use an
aggregate for member data pointers and are therefore currently
unsupported.

Unlike Itanium, the ms ABI uses 0 to represent null for polymorphic
classes.  Non-polymorphic classes use -1 like Itanium, since 0 is a
valid field offset.

For constructors/desctructors that return 'this', if there exists a callsite
that returns 'this' and is immediately before the return instruction, make
sure we are using the return value from the callsite.

We don't need to keep 'this' alive through the callsite. It also enables
optimizations in the backend, such as tail call optimization.

it wasn't taking into account that the float should be truncated *before* the
range check happens. Thus (unsigned)-0.99 and (unsigned char)255.9 have defined
behavior and should not be trapped.

I have filed http://llvm.org/bugs/show_bug.cgi?id=15538 against clang.
This code is safer anyway because "cast" assumes you really know that
it's okay to make the cast. In this case isa should not be false and
dyn_cast should not return null as far as I understand. But everything
else is valid so I did not want to revert my previous patch for attributes
mips16/nomips16 or use an llvm_unreachable here which would make a number
of our tests fail for mips.

(GDB gets confused if we break an expression into multiple debug

full experience people can still use -gcolumn-info.)

The back-end cannot differentiate between functions that are from a .ll file and
those generated from the front-end. We cannot then take the non-precense of
these attributes as a "false" value. Have the front-end explicitly set the value
to 'true' or 'false' depending upon what is actually set.
