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.
