Teach PHIElimination to handle <undef> operands.
...
When a PHI use is <undef>, don't emit a copy in the predecessor block,
but insert an IMPLICIT_DEF instruction instead. This ensures that
virtual register uses are always jointly dominated by defs, even if some
of them are IMPLICIT_DEF.

Handle <undef> operands in TwoAddressInstructionPass.
...
When the source register to a 2-addr instruction is undefined, there is
no need to attempt any transformations - simply replace the source
register with the destination register.
This also comes up when lowering IMPLICIT_DEF instructions - make sure
the <undef> flag is moved to the new partial register def operand:
%vreg8<def> = INSERT_SUBREG %vreg9<undef>, %vreg0<kill>, sub_16bit
rewrite undef:
%vreg8<def> = INSERT_SUBREG %vreg8<undef>, %vreg0<kill>, sub_16bit
convert to:
%vreg8:sub_16bit<def,read-undef> = COPY %vreg0<kill>

%RCX is not a function live-out in eh.return functions.

The function live-out registers must be live at all function returns,

than what LLVM would choose by default. For example, a variable
might be declared as
@x = thread_local(initialexec) global i32 42

If the specified model isn't supported by the target, or if LLVM can
make a better choice, a different model may be used.
