Nathan Slingerland aa5702d92b [llvm-profdata] Change instr prof counter overflow to saturate rather than discard 
Summary: This changes overflow handling during instrumentation profile merge. Rathar than throwing away records that would result in counter overflow, merged counts are instead clamped to the maximum representable value. A warning about counter overflow is still surfaced to the user as before.
