[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 correctly reports error message`

[BOLT][NFC] Speedup merge-fdata (#119942) Eliminate splitting the buffer into lines, and use `std::getline` directly. Simplify no_lbr and boltedcollection handling as well. Test Plan: For a large fdata file (200MB), fstream version is ~10% faster. 2024-12-14 22:26:20 -08:00			`# CHECK: cannot mix profile with and without no_lbr`
