Dean Michael Berris 90a46bdec2 [XRay] Bug fixes for FDR custom event and arg-logging
Summary:
This change has a number of fixes for FDR mode in compiler-rt along with
changes to the tooling handling the traces in llvm.

In the runtime, we do the following:

- Advance the "last record" pointer appropriately when writing the
  custom event data in the log.

- Add XRAY_NEVER_INSTRUMENT in the rewinding routine.

- When collecting the argument of functions appropriately marked, we
  should not attempt to rewind them (and reset the counts of functions
  that can be re-wound).

In the tooling, we do the following:

- Remove the state logic in BlockIndexer and instead rely on the
  presence/absence of records to indicate blocks.

- Move the verifier into a loop associated with each block.
