c370129daa Speedup bitcode writer. Do not walk all values for all functions to emit function local metadata. In one testcase, probably worst case scenario, the 70x speed up is seen.

f0226fee37 Slightly change the meaning of the reMaterialize target hook when the original 
instruction defines subregisters.

Any existing subreg indices on the original instruction are preserved or
composed with the new subreg index.

Also substitute multiple operands mentioning the original register by using the
new MachineInstr::substituteRegister() function. This is necessary because there
will soon be <imp-def> operands added to non read-modify-write partial
definitions. This instruction:

  %reg1234:foo = FLAP %reg1234<imp-def>

will reMaterialize(%reg3333, bar) like this:

  %reg3333:bar-foo = FLAP %reg333:bar<imp-def>

Finally, replace the TargetRegisterInfo pointer argument with a reference to
indicate that it cannot be NULL.

c4b5d67cdc Don't try to custom-lower 64-bit add-with-overflow and friends on x86-32; the 
x86 backend currently doesn't know how to handle them.

This doesn't really fix anything because LegalizeTypes doesn't know how to
handle them either.  We do get a better error message, though.

71a27d5aa6 DwarfWrite is now smart enough to drop debug value pointing to undefined register. Update this test to avoid this. 
iSel not properly lowring argument into a well formed DBG_VALUE in some cases is a separate issue and not related to the test in this testcase.
