Do not use host floating point types when emitting
...
ASCII IR; loading and storing these can change the
bits of NaNs on some hosts. Remove or add warnings
at a few other places using host floating point;
this is a bad thing to do in general.

unsigned test(unsigned a) {
return ~a;

llvm used to generate:
movl $4294967295, %eax
xorl 4(%esp), %eax
Now it generates:
movl 4(%esp), %eax
notl %eax
It's 3 bytes shorter.

Remove SDNode's virtual destructor. This makes it impossible for
...
SDNode subclasses to keep state that requires non-trivial
destructors, however it was already effectively impossible,
since the destructor isn't actually ever called. There currently
aren't any SDNode subclasses affected by this, and in general
it's desireable to keep SDNode objects light-weight.
This eliminates the last virtual member function in the SDNode
class, so it eliminates the need for a vtable pointer, making
SDNode smaller.
