  [BOLT] Testcase to repro dyn reloc bug

Add a new testcase that shows a bug in BOLT when writing out
dynamic relocations. This is currently marked as XFAIL as we work on
solving it. This bug happens when the current strategy fails to
recognize that the original dynamic relocation in the input should
reference the original .bolt.org.rodata section instead of the new one
.rodata created by BOLT after moving jump tables. This bug started
happening after 729d29e167a5.
