perf/x86/intel: Support Haswell/v4 LBR format
Haswell has two additional LBR from flags for TSX: in_tx and
abort_tx, implemented as a new "v4" version of the LBR format.
Handle those in and adjust the sign extension code to still
correctly extend. The flags are exported similarly in the LBR
record to the existing misprediction flag
