Subzero: Fix emission of global initializers.

Also changes the szbuild.py script to add -fdata-sections, and entirely removes the -disable-globals option.

The global initializer emission basically copies what llc does, based on 3 properties of the global: constant vs non-constant, internal vs external, and full zero-initializer vs non-trivial initializer.

BUG= none
