backends and removes the virtual declaration. With that out of the way
I should be able to cleanup one backend at a time.

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.

98290734b0 Properly compose subregister indices when coalescing. 
The comment about ordering of subreg indices is no longer true.
This exposed a bug in the new substVirtReg method that is also fixed.

da677f56f2 Fix PR7272: when inlining through a callsite with byval arguments, 
the newly created allocas may be used by inlined calls, so these
need to have their tail call flags cleared.  Fixes PR7272.

14bf35ae45 fix PR6623: when optimizing for size, don't inline memcpy/memsets 
that are too large.  This causes the freebsd bootloader to be too
large apparently.

It's unclear if this should be an -Os or -Oz thing.  Thoughts welcome.
