  [BOLT] Add test case triggering JT assertion

Current case that triggers BOLT assertion. Marked XFAIL.
In this test case, we reproduce the behavior seen in gcc where the
base address of a jump table is decremented by some number and ends up
at the exact addess of a jump table from another function. After
linking, the instruction references another jump table and that
confuses BOLT.
