LiveIntervals already adds <imp-def> operands for super-registers when a subreg
def defines the whole register. Thus, it is not necessary to do it again when
rewriting.

In fact, the super-register imp-defs caused miscompilations because the late
scheduler couldn't see that the super-register was read.

We still add super-reg <imp-use,kill> operands when rewriting virtuals to
physicals.

Small help text fixes, to make it more consistent and accurate.

Temporarily remove -l option from 'expr' command (at Sean's request).

register must be one of the destination registers for the load. Otherwise,
the tLDM instruction will write-back to the base register, which isn't what's
desired (otherwise, we'd have a t2LDM_UPD instead).

has_nothrow_copy_constructor hooked up to clang.  Filed http://llvm.org/bugs/show_bug.cgi?id=8107 to take care of several types which don't work yet.  If there is some reason we don't want to handle these types in the compiler, I can handle most of them in the library.

(i.e., leave the value the same, so that a new
stack frame will be linked to the previous
stack) rather than zeroing out RBP.

This fixes calls to dlopen(), for example, which
does a backtrace to see which image is calling
it.

turning (fptrunc (sqrt (fpext x))) -> (sqrtf x)  is great, but we have
to delete the original sqrt as well.  Not doing so causes us to do 
two sqrt's when building with -fmath-errno (the default on linux).
