Place the LSDA into the TEXT section for x86 Darwin. If the global it's pointing

to is local to the translation unit, we need to place fill the value of that
symbol into the non-lazy pointer.

This should conclude all Darwin changes for placing the LSDA into the TEXT
section. There is some cleanup to do. I.e., there's no longer a special need for
target-specific code here. But that can come later.
