[BOLT][merge-fdata] Fix basic sample profile aggregation without LBR info (#118481) When a basic sample profile is gathered without LBR info, the generated profile contains a "no-lbr" tag in the first line of the fdata file. This PR fixes merge-fdata to recognize and save this tag to the output file. 2024-12-13 17:28:37 +01:00			`## Check that merge-fdata tool doesn't falsely print no_lbr when not in no-lbr mode`

[BOLT] Fix counts aggregation in merge-fdata (#119652) merge-fdata used to consider misprediction count as part of "signature", or the aggregation key. This prevented it from collapsing profile lines with different misprediction counts, which resulted in duplicate `(from, to)` pairs with different misprediction and execution counts. Fix that by splitting out misprediction count and accumulating it separately. Test Plan: updated bolt/test/merge-fdata-lbr-mode.test 2024-12-14 22:38:24 -08:00			`# CHECK: 1 main 0 1 main 2 1 3`
