Make use of BSS more explicit in global initializers (vs a local .comm).

This reduces the number of conditionals, and will more closely reflect
the structure of the ELF writer's version of the same thing.
Without fdata-sections, the ELF writer version will have to batch all
initializers of a certain type so that they can be contiguous on the file
and the overall alignment can be determined.

A downside of this is that, .s files will be different from llc's output.
The spec .o and executables are identical before/after the change.
