Some basic tests for supplementing instrumentation profile with sample profile for static funcs.

RUN: llvm-profdata merge -supplement-instr-with-sample=%p/Inputs/NoFUnique.afdotext -suppl-min-size-threshold=2 %p/Inputs/NoFUnique.proftext -o %t1
RUN: llvm-profdata show -function=foo -counts %t1 | FileCheck %s

RUN: llvm-profdata merge -supplement-instr-with-sample=%p/Inputs/FUnique.afdotext -suppl-min-size-threshold=2 %p/Inputs/FUnique.proftext -o %t2
RUN: llvm-profdata show -function=foo -counts %t2 | FileCheck %s

RUN: llvm-profdata merge -supplement-instr-with-sample=%p/Inputs/NoFUnique.afdotext -suppl-min-size-threshold=2 %p/Inputs/FUnique.proftext -o %t3
RUN: llvm-profdata show -function=foo -counts %t3 | FileCheck %s

RUN: llvm-profdata merge -supplement-instr-with-sample=%p/Inputs/FUnique.afdotext -suppl-min-size-threshold=2 %p/Inputs/NoFUnique.proftext -o %t4
