[Rahman Lavaee via Phabricator via llvm-commits]

rahmanl added a comment.

Fix exception handling on PIC targets (Credit to @amharc for implementing the fix).

The idea is to use pc-relative encoding for LPStart in PIC mode, as absptr is
not possible.
The existing tests are updated to exercise the PIC mode.
