Tests for weighted merge of instrumented profiles.
1- Merge the foo and bar profiles with unity weight and verify the combined output
-RUN: llvm-profdata merge --instr %p/Inputs/weight-instr-bar.profdata:1 %p/Inputs/weight-instr-foo.profdata:1 -o %t
-RUN: llvm-profdata show --instr -all-functions %t | FileCheck %s --check-prefix=WEIGHT1
