[cmake] Avoid rel+asserts warnings when passing -UNDEBUG

MSVC 2012 gives warning D9025, "overriding /D NDEBUG with -UNDEBUG".
Removing the original definition of NDEBUG silences this.

DW_FORM_sec_offset should be a relocation on platforms that use
a relocation across sections. Do this for DW_AT_stmt list in the
skeleton CU and check the relocations in the debug_info section.

Add a FIXME for multiple CUs.

A few were missed in r178972.

Fix PR15674 (and PR15603): a SROA think-o.

The fix for PR14972 in r177055 introduced a real think-o in the *store*
side, likely because I was much more focused on the load side. While we
can arbitrarily widen (or narrow) a loaded value, we can't arbitrarily
widen a value to be stored, as that changes the width of memory access!
Lock down the code path in the store rewriting which would do this to
only handle the intended circumstance.

All of the existing tests continue to pass, and I've added a test from
the PR.
