Chandler Carruth 736f9fd229 Revert three patches which were committed without explicit contribution
by their authors.

This may break builds where others added code relying on these patches,
but please *do not* revert this commit. Instead, we will prepare patches
which fix the failures.

Reverts the following commits:
r168306: "[asan] support x32 mode in the fast stack unwinder. Patch by H.J. Lu"
