[PATCH] D41705: Place undefined globals in .bss instead of .data

[Eli Friedman via Phabricator via llvm-commits]

Please post diffs with context (see https://llvm.org/docs/Phabricator.html#requesting-a-review-via-the-web-interface).

Needs a regression test (probably in test/CodeGen/X86), to show that we are in fact generating the expected code.

Does this do the right thing for constant structs which have some null and some undef members?
